摘要：
Ab initio calculations are performed for the system N2-He*(2 3S) --> N2+ (2)SIGMA(g), (2)PI(u), (2)SIGMA(u)) + He + e-. Potential curves are calculated for the entrance resonance state and the exit ionized states. An energy width for each ionization is also calculated. It is found that energy widths are governed by the overlap of the He* 1s orbital with the orbital of the target molecule from which the electron is released. The calculations are consistent with the experimental results for the state-resolved collision energy dependence of Penning ionization cross sections for this system.
