Using the transport theory approach, equations are derived for the angular dependence of XPS intensities from semi-infinite solids taking into account elastic scattering of photoelectrons and non-dipolar transitions. The unpolarized, linearly polarized, and partly polarized excitation sources are co

โฆ Synopsis
The relativistic calculations of non-dipolar angular parameters d and g as well of dipole parameter b for all shells of atoms from Li to Ar are performed. The photoelectron kinetic energy is taken in the range from 100 to 5000 eV. The trends of calculated values are discussed. The theoretical values are compared with existing experimental data. It is shown that the non-dipolar transitions have a strong influence on the photoelectron angular distribution and can lead to an extremum, which is absent in dipole approximation.
