计算了质子（H+, D+, T+）在氦和质子（H+, D+, T+）和氢原子（H， D， T）的对称组合（H， D， T）在质能范围0.1 ~ 100 eV的中心弹性散射的微分截面和积分截面。此外，我们从弹性微分截面中导出了用于等离子体输运研究的动量传递和粘度截面，并计算了电荷传递截面。在这些计算中使用了全量子和半经典方法，以及非常精确的电子势能曲线。结果与现有数据进行了比较。
Differential and integral cross sections are calculated in the centre of mass energy range 0.1-100 eV for elastic scattering of protons (H+, D+, T+) by helium and of symmetric combinations of protons (H+, D+, T+) and hydrogen atoms (H, D, T) by hydrogen atoms (H, D, T). In addition, we derive from the elastic differential cross sections the momentum transfer and viscosity cross sections of use in the study of plasma transport, and compute the charge transfer cross section. Fully quantal and semiclassical approaches are utilized in these calculations, as are very accurate electronic potential energy curves. The results are compared with available data.
