这份报告描述了利用一种技术测量离子-分子反应的截面，该技术涉及从质量和动能两个方面预先选择初级离子。给出了反应Ar+D2→ARD++D，N2++D2→N2D++D，H2++H2→H3++H，D2++N2→N2D++D，H2++He→HeH++H，D2++Ar→ARD++D的截面作为离子动能的函数。前两个反应的截面行为与后四个反应截然不同，可视为氢离子转移的情况。与以前的测量结果进行了比较，显示出相当的一致性；然而，与现有理论的一致性相当差。
This report describes measurements of cross sections for ion—molecule reactions by use of a technique which involves preselection of the primary ion in terms of both mass and kinetic energy. Cross sections as functions of ion kinetic energy are given for the reactions Ar++D2→ArD++D,N2++D2→N2D++D,H2++H2→H3++H,D2++N2→N2D++D,H2++He→HeH++H,D2++Ar→ArD++D. The behavior of the cross sections for the first two of these reactions, which can be considered to involve hydrogen atom transfer, is strikingly different from that of the remaining four, which can be taken as cases of hydrogen ion transfer. The comparison with previous measurements shows fair agreement; however, agreement with existing theories is rather poor.
