A program for computing weak and intermediate field Zeeman splittings from MCHF wave functions

Jönsson, Per LU and Gustafsson, Stefan (2002) In Computer Physics Communications 144(2). p.188-199
Abstract
Given electronic wave functions generated by the MCHF_CI program (LSJ format), this program calculates diagonal Lande a factors that determine separations of magnetic sublevels in weak external magnetic fields. In addition the program computes off-diagonal Lande factors and constructs the total interaction matrix for an atom in a magnetic field. By diagonalizing the interaction matrix and plotting the eigenvalues as functions of the magnetic field, Zeeman structures beyond the weak field limit are obtained.
