27 th International Symposium on Ion‑Atom Collisions
14-16 July 2021 | Organized On-line

The International Symposium on Ion-Atom Collisions (ISIAC) is a biennial satellite of the International Conference on Photonic, Electronic and Atomic Collisions (ICPEAC). As usual, the symposium will cover all ion-atom collision phenomena including excitation, ionisation and charge transfer, from low to relativistic velocities as well as interactions of ions with surfaces, molecules and clusters.

Dear colleague,

You are cordially invited to the 27th International Symposium on Ion-Atom Collisions (ISIAC) organized on-line by the Faculty of Physics of the Babeș-Bolyai University, Cluj, Romania on 14-16 July, 2021 (https://atom.ubbcluj.ro/isiac). ISIAC is a biennial satellite of the International Conference on Photonic, Electronic and Atomic Collisions (ICPEAC). As usual, the symposium will cover all ion-atom collision phenomena including excitation, ionisation and charge transfer, from low to relativistic velocities as well as interactions of ions with surfaces, molecules and clusters.

Unfortunately, this year is not possible to meet in person because of the COVID-19 pandemics. In this situation the International Advisory Committee of ISIAC has decided to organize a virtual meeting.

The program each day will consist of two sessions, shorter than usual, in order to facilitate the participation from all time zones. Beside the invited talks (already listed here) there will be selected a number of contributed talks from the submitted abstracts. There will be contributed talks of 10 minutes (short talks) and of 5 minutes (flash presentations). Poster session (not very effective in the virtual mode) will be organized only, if an important number of high-quality abstracts do not fit into the program.

The abstract submission page is already open. Submission deadline is May 14. Please, consider to submit your abstract to the 27th ISIAC.

In order to cover the cost for the technical organization of the meeting, there will be a registration fee, payable on-line by credit card (40 EUR for regular participants, 20 EUR for students). Only registered participants will have the opportunity to present their contribution, and will have their abstracts included into the Abstract book (to be published on the web page of the meeting).

The registration page will open on April 15. Participants with accepted abstracts will be requested to register till June 21, in order to be included into the program.

If you have any questions, please, do not hesitate to contact me.

See you virtually at the meeting,

Prof. Ladislau Nagy
local chair
