评估了由入射能量在 44.2 eV 和 217.6 eV 之间的电子撞击引起的 He+ 中 1s-2s 和 1s-2p 跃迁的激发截面。使用的基本方法是紧耦合近似，其中 He+ 的 1s、2s 和 2p 态保留在总波函数的适当对称展开中。对本征函数展开收敛性的初步研究表明，这里的结果比氢中的结果要准确得多。还研究了先前计算的准确性。
The excitation cross sections for the 1s-2s and 1s-2p transitions in He+ induced by impacting electrons with incident energies between 44.2 eV and 217.6 eV are evaluated. The basic method used is the close-coupling approximation where the 1s, 2s and 2p states of He+ are retained in an appropriately symmetrized expansion of the total wave function. Preliminary investigations of the convergence of the eigenfunction expansion indicate that the results here are much more accurate than in hydrogen. The accuracy of previous calculations is also investigated.
