Study of photon-induced L_3 vacancy alignment for elements La to U

摘要

Alignment of photon-induced L3 vacancies is studied in rare earth and high Z elements at energies of experimental interest, neax thresholds to 60 keV, under non-relativistic dipole approximation. Numerical calculations of the matrix element are undertaken to produce theoretical data for comparison with the experimental findings. The A_2 values being > 0.1 at photoelectron energies < 20 keV are certainly higher than 5-8% uncertainties quoted in experimental results. Present findings are from a very basic model, hydrogen-like and can further be treated as reference to observe the impact of screening, relativistic, multipole and retardation corrections to the model.
