摘要：

We present the first ab initio calculations of electron-energy and angular distributions of saddlepoint and S-promotion electrons for ionization in proton-hydrogen atom collisions. The calculations are based on outgoing wave Sturmian expansions in the frequency domain. They go beyond the usual Born-Oppenheimer separation of electron and nuclei motion and display the ''v/2'' peaks and the continuum capture cusps, missing in previous theories.
