Abstract

The 4s4p configuration of Zn is analyzed using the Relativistic jj-coupling approach. The experimentally determined relativistic Slater integrals are compared with the results of numerical codes, both quasi- and fully-relativistic ones. In this work, they are estimated, semi-empirically, the two J = 1 levels up Z = 70 and the ¹P₁ level up Z = 92 by judicious interpolation and extrapolation of energies. The comparison with extensive relativistic configuration-interaction calculations indicates that differences between both approaches are of the order of measurement accuracies.
