测量了Ar{sup {ital q}+}+H{sub 2}在{ital q}=6、7、8、9和11时，抛射能量从{ital q} eV到{ital q} keV的单电子捕获截面，包括转移电离和双电子捕获截面。用分子轨道展开法在240 ~ 80 keV范围内计算了Ar{sup 6+}和Ar{sup 8+}的碰撞截面，与实验结果吻合较好。在实验和理论中发现，单电子捕获截面比双电子捕获截面大一个数量级以上。单电子捕获截面也与朗之万截面进行了比较，朗之万截面是穆勒和萨尔兹伯恩[物理学家]提出的一种标度定律。[j] .地球物理学报，1999,17(1):1 - 2。
The cross sections for single-electron capture, including transfer ionization, and for double-electron capture, have been measured for Ar{sup {ital q}+}+H{sub 2} for {ital q}=6, 7, 8, 9, and 11 with projectile energies from {ital q} eV to {ital q} keV. Theoretically, the cross sections for Ar{sup 6+} and Ar{sup 8+} impact were calculated using a molecular-orbital expansion method in the energy region from 240 eV to 80 keV, and are in good agreement with experiment. The single-electron-capture cross sections were found to be more than one order of magnitude larger than those for double capture in both experiment and theory. The single-electron-capture cross sections were also compared to the Langevin cross section, a scaling law developed by Mueller and Salzborn [Phys. Lett. 62A, 391 (1977)], and the absorbing sphere model.
