在平面波玻恩近似下，利用原子电子的相对论狄拉克函数，计算了重荷粒子碰撞下的K壳层电离截面。利用K壳层电子的相对论波函数，并考虑了库仑偏转效应，估算了入射电子的结合能增加效应。数值计算结果与非相对论平面波玻恩近似、相对论半经典近似以及实验数据进行了比较。
The K-shell ionization cross sections by heavy charged-particle impact are evaluated in the plane-wave Born approximation, using relativistic Dirac functions for the atomic electrons. The effect of binding-energy increase due to the projectile is estimated by the use of relativistic wave functions for K-shell electron and the Coulomb-deflection effect is also taken into account. Numerical results are compared with the corresponding values of the nonrelativistic plane-wave Born approximation and the relativistic semiclassical approximation as well as the experimental data.
