Photoeffect in the 5d, 6s, and 6p subshells of atomic lead between 25 and 110 eV
Partial cross sections sigma and angular distribution parameters ..beta.. were measured for the 5d subshell of atomic lead between 25 and 110 eV, and for the major components of the 6s and 6p subshells between 25 and 55 eV. Data are compared with Dirac-Slater (DS) calculations. Good agreement is found for the ..beta.. values of both the 5d and 6p subshells. However, as characteristic for single-particle models, the 5d delayed cross-section maximum is seen to be too high. The theoretical DS cross section sigma(6p/sub 1/2/) follows our data satisfactorily, but the DS sigma(6s) and the DS ..beta..(6s) do not. Earlier experimental data for Pb are in satisfactory agreement with the present 5d and 6p data. A comparison of our Pb data with experimental data for Hg and relativistic random-phase approximation results for the 5d and 6s subshells of Hg shows a generally satisfactory accord.
