Setup for improved resolution in ion-molecule crossed beam imaging — •Jerin Judy, Dasarath Swaraj, Tim Michaelsen, Fabio Zappa, Robert Wild, and Roland Wester — Institut für Ionenphysik und Angewandte Physik, Universität Innsbruck, Innsbruck, Austria.

Crossed-beam experiments have proven to be a powerful tool for investigating reaction dynamics in the gas-phase [1]. Our group specializes in the study of ion-molecule reactions in combination with a velocity map imaging (VMI) spectrometer to record energy and angle dependent differential cross-sections [2]. Currently we focus on reactions involving laser ionized hydrogen molecules with argon using a newly commissioned crossed-beam experiment, where our aim is to resolve the different vibrational levels in the molecular products. We will present preliminary results on this system and describe the new experimental setup.
