Calculation of the Hyperfine Structure and g_J Values of the 3d^94s4p Configuration of Copper

Abstract

Wave functions that take into account departures from LS coupling and configuration interaction are obtained for the 3d94s4p configuration of copper by treating the radial integrals as parameters and adjusting them to fit the experimental energy levels. The relativistic dipole and quadrupole hfs matrix elements between all levels of the same J within the 3d94s4p configuration are derived. The hfs and gJ values of most states of the 3d94s4p configuration are then obtained by evaluating these matrix elements with the derived wave functions. Good agreement between calculated and most experimental hfs and gJ measurements is obtained. The quadrupole moment of 63Cu obtained from the d hole is −0.267b and from the p electron is −0.184b. Sternheimer corrections are not included.
