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.

提出用快速抛射体研究氢分子电离加激发的双电子过程，验证雷丁和福特的理论。提出了三种测量方法：(1)不同激发态的激发截面，作为弹丸速度和电荷的函数以及作为核间轴方向的函数，旨在了解玻恩的高贡献和非偶极相互作用的重要性。(2)电荷捕获加上激发到偶极允许态和非偶极允许态的截面，以及电荷捕获加上电离的截面，旨在说明快或慢连续电子的重要性。(3)电离碰撞中产生的激发氢分子离子态与喷射电子的相关性。
