Dissociative double capture in 15N7+ and H2 collisions

Because of the high potential energy (up to 30 keV/u) and the low velocity of the ions from the ECR-Source, the main reaction channel in collisions with atoms or molecules is electron capture. The experimental set up will be designed for single capture and double capture with Coulomb explosion in molecules, e specially for the following reactions: 15N7++H2→15N5++H++H+. The highly charged projectile passes the target molecule in a random distance where Rutherford- and atomic scattering are possible reactions. When the projectile scatters on an electron or the core of the molecule it can be detected out of the center of the beam with a time- and position sensitive MCP-Detector with delay-line a node. The deflection angle of the projectile is a parameter how close the projectile passes the target molecule. The knowledge of this impact parameter is one big advantage of ion-atom and ion-molecule experiments compared to photon-atom or photon-molecule interactions
