Differential Cross Section Minima for Elastic Scattering of Electrons by Krypton Atoms in the Energy Range 0–500 eV

摘要

Elastic scattering of 0- to 500-eV electrons by krypton atoms is studied in terms of a model of phenomenological real potential with allowance for spin–orbit interaction. The energy dependences of the angular positions of differential cross section minima are calculated and compared with experimental data. The energies and angular positions of seven critical points where the differential cross sections reach minimal values are determined. The results obtained are in good agreement with the available experimental data.
