AMO Seminar

Title: Cold and controlled collision experiments with Coulomb-crystallised ions

Speaker: Prof. Stefan Willitsch, Chemistry Department, Universität Basel

Time: Thursday, Jan. 24th, 15:15

Place: Phys. Aud.



Recent advances in the cooling and state preparation of atomic and molecular ions in traps have opened up opportunities to study collisional and reactive processes at an unprecedented level of detail and control. We will present new results on reactive collisions between atomic and molecular ions with ultracold atoms at millikelvin temperatures to highlight the unusual features of cold ion-neutral interactions. We will also discuss recent results on studies of chemical reactions between fully state-prepared, sympathetically cooled molecular ions and internally cold neutral molecules at precisely defined collision energies illustrating the exquisite level of detail at which molecular interactions can be studied using Coulomb-crystal techniques. The talk will conclude with an outlook on future developments in the field.

Coffee, tee and cake will be served at 15:05.

Annette Svendsen, Jacob Sherson and Aurelien Dantan
