Photoelectron angular distribution parameters for elements Z=1 to Z=54 in the photoelectron energy range 100-5000 eV

Parameters of the angular distribution of photoelectrons along with the sub shell photoionization cross sections calculated for all subshells of atoms with 1 less than or equal to Z less than or equal to 54 are presented in th e Table for nine photoelectron energies in the range 100-5000 eV. Relativis tic treatment of the photoeffect is used. The calculations have been perfor med within the quadrupole approximation with the central Dirac-Fock-Slater potential. The hole left by the emitted electron has been taken into accoun t in the framework of the frozen orbital approximation. Applications of non dipolar parameters to photoelectron angular distribution in solids, to quan titative x-ray photoelectron spectroscopy analysis, and to the x-ray standi ng wave method are discussed.
