We are using the Cold Target Recoil Ion Spectroscopy (COLTRIMS) to investigate the break up of CO₂ in impact processes with slow highly charged ions. While the slow highly charged ions passes the CO₂ molecule electron capture into the projectile causes a conformation change of the CO₂ molecule. With the COLTRIMS set up we are able to measure the 4π solid angle in momentum space of the dissociating ion fragments. The motivation for this experiment is to ascertain the change of the CO₂ molecule conformation.
