Two-Electron Processes in Ionizing Collisions with Hydrogen Molecules (Physics)

提出了用快速入射粒子研究氢分子的电离加激发的双电子过程，验证了Reding和Ford的理论。提出了三个测量：(1)各种激发态的激发截面，作为入射速度和电荷的函数，以及作为核间轴取向的函数，旨在理解更高的玻恩贡献和非偶极相互作用的重要性。(2)电荷俘获加激发到偶极允许态和非偶极子允许态的截面，以及电荷俘获加电离的截面，旨在说明快或慢连续电子的重要性。(3)在电离碰撞中形成的出射电子与激发氢分子离子状态之间的关联。

It is proposed to study the two-electron process of ionization plus excitation of the hydrogen molecule by fast projectiles, testing the theory of Reading and Ford. Three measurements are proposed: (1) Cross sections for excitation of various excited states, as a function of projectile velocity and charge and as a function of orientation of the internuclear axis, intended to understand higher Born contributions and the importance of nondipole interactions. (2) Cross sections for charge capture plus excitation to dipole allowed and nondipole allowed states, as well as charge capture plus ionization, intended to illustrate the importance of a fast or slow continuum electron. (3) Correlation between ejected electron and excited hydrogen molecular ion state formed in an ionizing collision.
