Elastic scattering of electrons and positrons by atoms. Schrödinger and Dirac partial wave analysis

Abstract
Two FORTRAN 77 codes are described which provide a complete description of elastic scattering of electrons and positrons by atoms using the static field approximation with non-relativistic (Schrödinger) and relativistic (Dirac) partial wave analysis. The delivered information includes phase shifts, differential cross-sections, scattering amplitudes and percentage points of the single scattering angular distribution. The scattering field may be internally generated by the codes (which incorpor...

摘要
本数据集介绍了两款FORTRAN 77代码，可通过静态场近似（static field approximation）结合非相对论（薛定谔（Schrödinger））与相对论（狄拉克（Dirac））分波分析法（partial wave analysis），完整描述原子对电子与正电子的弹性散射（elastic scattering）过程。所输出的信息包含相移（phase shifts）、微分截面（differential cross-sections）、散射振幅（scattering amplitudes）以及单次散射角分布（single scattering angular distribution）的百分点数值。散射场可由代码内部生成（其整合……）
