โœฆ Synopsis


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 considered. The elastic scattering smeared the non-dipolar angular contribution in complete analogy with smearing of dipole contribution. The non-dipolar contribution has nonnegligible effect on angular photoelectron distribution and must be taken into account. The Monte-Carlo calculations are in agreement with transport theory approach.
