Evaluation of Effective Operators for Configuration Interaction
Year: 1970
Type: article
Abstract: Corrections to the Hartree-Fock Slater integrals due to electrostatic configuration interaction are calculated for the 4 f2 configuration of Pr IV using perturbation theory and graphical methods. The Trees parameter α and the additional parameters β and γ are also calculated. To second order the interaction with 27 bound configurations and 8 single particle excitations to the continuum give F2 = 88 963,14, F4 = 61 000.08, F6 = 33 353,80. This may be compared with empirical values F2 = 72 549, F4 = 53 874, F6 = 35 973, α = 24, β = 586, γ = 728.
