本文首次计算了质子-氢原子碰撞电离过程中鞍点电子和促进电子的能量和角分布。计算是基于在频域中的传出波Sturmian展开。它们超越了通常的电子和原子核运动的玻恩-奥本海默分离,并显示了在以前的理论中缺失的“{italv}/2 "峰和连续捕获尖点。
We present the first {ital ab} {ital initio} calculations of electron-energy and angular distributions of saddle-point and {ital 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 ``{ital v}/2`` peaks and the continuum capture cusps, missing in previous theories.
