Message from the organizers

We warmly thank the delegates, accompanying persons, sponsors and exhibitors who took part in the 31st International Conference on Photonic, Electronic and Atomic Collisions (ICPEAC XXXI) in Caen and Deauville, France, from 23 to 30 July 2019 at the University of Caen Normandie for the first day of Tutorials and then at the Deauville International Conference Centre. This conference continued the sixty-year history of the ICPEAC series which began in New York, USA, in 1958 and held biennially since 1961.

With an attendance of 615 participants, including 32% of early-career researchers, ICPEAC XXXI brought together world's leading scientists who worked actively in the fields of collisions involving photons, electrons, ions, atoms, molecules, clusters, surfaces, and exotic particles. The ICPEAC XXXI scientific program was carefully selected by the International Program Committee. It was led by distinguished tutorial and plenary lecturers who introduced and highlighted the recent discoveries in their field of research. The winners of the IUPAP Young Scientist Prize in Atomic, Molecular and Optical Physics presented their remarkable achievements in one of the plenary session. This was followed by 62 progress reports which gave further details and in-depth analysis of many important works. Close to 795 original presentations were scheduled in 5 poster sessions with the best poster selected daily by the popular vote and 28 "hot topic" presentations promoted to oral talks.

The ICPEAC XXXI tutorials and the main conference were strongly supported by the conference sponsors which made possible to organize this event under very good conditions. They were looked after by professional and dedicated teams of conference logistics from both hosting locations who made the conference program running smoothly. The Local Organizing Committee is very thankful to all of them.

The delegates and guests enjoyed the social program, including gastronomy and wine during the Welcome Reception and Conference Dinner. They were immersed in the mazes of ancient Rome, thanks to virtual reality techniques developed by a well-known laboratory in Caen. The week-end was dedicated to excursions tours allowing to discover not only the delightful resort of Deauville, regarded as the “Queen of the Norman beaches”, but also the whole heritage offered by the Normandy territory.

We very much hope that you appreciated your attendance at the ICPEAC XXXI and you had been both enlightened and entertained by the conference and its social activities.

ICPEAC is...

... a conference held every two years on four continents, which gathers 500 to 800 participants at each edition.

The conference brings together world's leading scientists who are actively working in the field of collisions involving photons, electrons, ions, atoms, molecules, clusters, surfaces, and exotic particles. The latest advances of the domain will be presented, such as ultrafast dynamics at the femto- or attosecond scale, ion-induced radiation damage in particular of biomolecules, atomic spectroscopy and molecular physics of antimatter, free electron lasers, particle acceleration generated by high-power lasers, or ultracold collisions.

Since 1995, ICPEAC around the World was in

Numbers indicate the participant's attendance.

The program will start with three Tutorial Lectures that will be held on the downtown Campus of the University of Caen Normandy.

In Deauville, the ICPEAC scientific program will consist of 5 Plenary Lectures, 63 Progress Reports, 26 Special Reports, and 5 Poster Sessions. Plenary talks are of general interest to all participants. Progress Reports and Special Reports will be arranged in two parallel sessions, and are intended to present recent work in different subfields. In particular, the Special Reports are selected from the submitted abstracts to showcase the most recent developments. Additionally, about 1000 Posters will be presented in five poster sessions, held either during morning or afternoon sessions. The conference language is English.

Broad topics will include, but are not limited to:

  • Photon impact (weak field)

Getting there

The tutorials will be hosted by the University of Caen Normandy on 23 July 2019

The University of Caen Normandy (UNICAEN) is a member of Normandie Université, a research and higher education cluster, gathering the universities of Caen, Rouen, Le Havre and the engineering schools of Caen (ENSICAEN) and Rouen (INSA).

It has about 30 000 students, and more than 2 000 researchers working in 46 research units. Its exceptional scientific environment includes the GANIL facility (Grand Accélérateur National d’Ions Lourds), the largest heavy-ion accelerator in France where researchers from around the world perform their experiments.

The downtown campus of the University of Caen Normandy is thus particularly suited to host the TUTORIALS of ICPEAC, which will be opened and free of charge for Master and PhD students as well as Postdocs coming from all over the world. Note that these tutorials will be accessible to anyone who is interested.

More detailed information about accommodation (list of hotels and apartments, booking) is available here.

Abstracts and Proceedings

The abstracts of invited talks (Tutorials, Plenary Lectures and Progress Reports), will be accessible in electronic version from the Book of Abstracts that will be posted on the Conference Website. They will also be published in the Conference Handbook distributed to the participants.

All speakers are invited to submit a paper that will be published in a regular issue of IOP Journal of Physics.

The Tutorial lectures will be published in Journal of Physics B: Atomic, Molecular and Optical Physics, and specific instructions will be sent by email.

The Plenary Talks, Progress Reports and Special Reports, will be published in a regular issue of Journal of Physics: Conference Series, an online open-access journal that is freely available without restriction (see the ICPEAC 2017 JPCS Proceedings). Guidelines concerning the preparation and the submission of the manuscript files (page limits, styles, etc.) are available here.

All the invited papers should be submitted in electronic version (PDF format) before July 23, 2019 to the e-mail address

In addition, two hardcopies of the manuscript have to be submitted at the registration desk of the conference.

Regular Abstracts, that have been submitted by 10 March 2019 (extended deadline) , will be reviewed by the ICPEAC Committees in April in order :

  • to be published on line as part of the Conference Proceedings in Journal of Physics: Conference Series unless authors have declined this publication
  • to be selected as Special Report to highlight the most recent developments. 26 Hot Topic Talks will be added to the Scientific Conference Program and the synopsis of those selected abstracts will appear in the Conference Handbook.

Post-deadline abstracts, submitted before 15 June 2019 have been reviewed by the Local Organizing Committee.

All accepted abstracts (Regular and Post-deadline) will be accessible in electronic version from the Conference Website and will appear in the Book of Abstracts. The list of all accepted regular abstracts will be published in the Conference Handbook.

Post-post deadline abstracts can still be sent to the Local Organizing Committee. Provided acceptance and available poster boards during the poster sessions, they could be displayed during the conference. They will neither appear in the Book of Abstracts nor in the Conference Handbook. Nevertheless and addendum will be printed and distributed to the ICPEAC 2019 participants.

Detailed instructions on post-post-deadline abstract preparation and submission can be found here.

Support policy

Financial Support Policy

Our general policy is to primarily help young researchers and students to attend the conference.

Limited funds will be certainly also available to support participants presenting invited talks or contributed posters. Participants from developing regions will be considered on our list of priorities.

Detailed instructions are available now to apply for a grant for Young Scientists, and for financial support for participants. The deadline to send those applications has been extended to 10 March 2019.


Two prestigious prizes for young scientists will be awarded at the XXXI ICPEAC in Deauville:

  • The IUPAP Young Scientist Prize in Atomic, Molecular, and Optical Physics,
  • The IUPAP Young Scientist Prize (YSP) of the IUPAP C15 Committee is granted to nominees, with not more than 8 years research experience (excluding career interruption) following the PhD, who have made original and outstanding contributions to the field of AMO Physics. Next July, during the XXXI ICPEAC, the 2019 YSP will be awarded to Andreas Mooser, from the Max-Planck Institute for Nuclear Physics & CERN and Christian Smorra, from CERN.

    Andreas Mooser and Christian Smorra have both been selected for their outstanding contribution to determine the most precise comparison of the proton-to-antiproton charge-to-mass ratios and the most precise comparison of the proton and antiproton magnetic moments, constituting two different world-record tests of the fundamental charge, parity, and time reversal symmetry in these systems. They will give a Plenary talk at the conference on those aspects in the morning of Monday July 29.

  • The Sheldon Datz Prize for an Outstanding Young Scientist attending ICPEAC.
  • The Sheldon Datz prize supports an outstanding young researcher to attend ICPEAC. Next July, during the XXXI ICPEAC, it will be awarded to Vincent Lemelin, from the Department of Nuclear Medicine and Radiobiology, Sherbrooke University, Canada.

    Vincent Lemelin, a PhD student in the group of Prof. Léon Sanche, has been selected by the ICPEAC officers for his work on the comprehension of radiation energy deposition in biological materials.
