用原子轨道强耦合方法研究H(1s)+H(2s)碰撞的反应截面

采用单电子的双中心原子轨道强耦合方法,计算了H(1s)+H(2s)碰撞体系H(2s)失去电子过程的总截面,并与前人的实验结果进行了比较.研究表明,采用双中心原子轨道强耦合方法得到的H(1s)+H(2s)体系H(2s)失去电子过程的截面与实验比较符合.同时,还给出了H(1s)+H(2s)碰撞体系H(2s)电离过程、H(1s)俘获电子过程和H(2s)退激发到H(1s)过程的理论截面.

The Reaction Cross Sections of H(1s) + H(2s) Collisions Investigated by Atomic Orbital Close-Coupling Method

The single-electron, two-centre atomic orbital close-coupling method is adopted to calculate electron-loss cross sections of in H(1s) + H(2s) collisions. The theoretical results are compared with experimental data. Our studies have shown that electron-loss cross sections of in H(1s) + H(2s) collisions calculated by the single-electron, two-centre atomic orbital close-coupling method are in good agreement with experimental data. The ionization and de-excitation cross sections of H(2s), and the capture cross sections of H(1s) in H(1s) + H(2s) collisions are also presented.
