Differential investigations of charge transfer processes in low energy ion-atom/molecule collisions

The progress of differential studies of ion-atom/molecule collisions using the reaction microscope was reported. The state-selective and angular differential cross sections were measured for slow ion-atom collisions. In this paper we focus on the two-electron processes, namely double electron capture and transfer ionization, occurring in the collisions of ion impact on two-electron target system of helium and molecular hydrogen, respectively. The molecule Coulomb explosions were investigated by employing the negative ion characteristic. The transfer momentum dependence of two-electron processes for He2+ and H+ impact on He and H2 were compared, and the kinetic energy release in Coulomb explosions induced by He2+ and H+ was measured.
