DATABASE OF RELATIVISTIC ELASTIC-SCATTERING CROSS-SECTIONS FOR CALCULATIONS OF PHOTOELECTRON AND AUGER-ELECTRON TRANSPORT

Quantitative applications of electron spectroscopies, AES and XPS, should be based on theoretical models describing realistically the electron transport in solids. Detailed knowledge of elastic scattering cross-sections due to the elements constituting a given solid is necessary in such calculations. To some extent, such data are available in the literature, but a complete data set in the form of a computer controlled database is not available. An extensive software packet is described in the present article for providing relativistic elastic scattering cross-sections for elements with atomic numbers up to 96. The energy range for each element varies from 50 to 10 000 eV in steps of 1 eV. The software packet has the following options: (1) visualization of the differential elastic scattering cross-sections in different coordinate systems; (2) creation of files containing the elastic scattering cross-sections for specified elements, energies, and coordinates; (3) creation of random number generators providing the polar scattering angles to be used in Monte-Carlo simulation of the transport of electrons in solids; and (4) testing the performance of the created random number generators.
