Ab initio calculation of charge transfer cross sections in C4++H2 collisions

We present calculations of state selected (vibrational and electronic) cross sections for single charge transfer in C4+ + H-2, D-2 and DT collisions in the energy range 50 eV amu(-1) < E < 2.5 keV amu(-1). Cross sections for transfer dissociation and Hz vibrational excitation reactions are also presented. We have employed ab initio electronic wavefunctions of the triatomic system, the eikonal method to treat the ion-diatom relative motion, and the sudden approximation for vibration and rotation of the diatom.
