HFS92: A program for relativistic atomic hyperfine structure calculations
Description
Abstract We describe a program for the computation of magnetic dipole and electric quadrupole diagonal (A_J , B_J ) and off-diagonal (A_(J.J-1), B_(J,J-1), B_(J.J-2)) hyperfine interaction constants. Approximate atomic wavefunctions are assumed to be linear combinations of configuration state functions, which are, in turn, constructed from four-component spin-orbitals to be many-particle eigenfunctions of the parity and angular momentum operators. Keywords: Atomic hyperfine structure; Atomic hyp... Title of program: HFS92 Catalogue Id: ADDN_v1_0 Nature of problem Prediction of atomic hyperfine structure using a 'fully relativistic' approach. Versions of this program held in the CPC repository in Mendeley Data ADDN_v1_0; HFS92; 10.1016/0010-4655(96)00057-4 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
