Solvay Workshop on
"Atomic and molecular collision mechanisms - ACME"

Brussels, 30 March - 2 April 2015

ULB - Campus Plaine - Solvay Room

The temperature at the Earth surface is about 300 K, then evolves down to some 150 K at the upper limit of the atmosphere. Even colder, extraterrestrial environments are well identified in the Solar system, down to 50 K e.g. in the atmosphere of Neptune. Temperature further drops between 10 and 20 K in the coma of comets and may even get lower in the interstellar medium. Molecules are present in all of these media, supporting chemistry, and the origin of life. Today, dedicated, sophisticated instrumental means allow the most extreme of these conditions to be matched and even exceeded in the laboratory. Collision mechanisms and their evolution with decreasing temperature are of primary relevance in the related reactive processes. For the lowest temperatures these mechanisms still remain to be fully unravelled and there is a need for continued progress in measurement and modelling. Chemistry at ultralow temperatures, the formation of dimers and larger aggregates, the understanding and active control of collision processes at the molecular level, and their atmospheric and astrophysical applications define a very active, challenging and multidisciplinary research field that lies at the heart of the ACME workshop.

Regular participants should take care of their hotel reservation.

Hotels that we often use for our visitors are Hôtel Astrid, Hôtel Atlas and Hôtel Opéra

Special issue in Molecular Physics

A special issue in Molecular Physics will be devoted to the workshop.

Participants and non participants to the workshop are welcome to submit a regular research paper.

The deadline for submission will be around May, 2015.


*The Special Issue in Molecular Physics is now available in ScholarOne. When submitting
the authors may select ‘Atomic and Molecular Collision Mechanisms’
on the list of Special Issues and Prof. T. Softley as Editor.
