Programs for computing LS and LSJ transitions from MCHF wave functions

Abstract
Given wave-function expansions for the initial and final state along with expressions for the transition matrix elements, the programs evaluate oscillator strengths and transition probabilities. The MCHF_LSTR program assumes wave functions are represented in the non-relativistic formalism and computers E1 and E2 transition data. The MCHF_LSJTR program requires wave-function expansions from a Breit-Pauli CI calculation and evaluates transition data for E1, E2, …, or M1, M2, …, transitions betw...

Title of program: MCHF_LSTR AND MCHF_LSJTR
Catalogue Id: ACBB_v1_0

Nature of problem
These programs are part of the MCHF atomic structure package [1] for bound state systems and evaluate transition data from MCHF wave function expansions. MCHF_LSTR performs non-relativistic calculations for E1 and E2 transitions between a pair of LS states. MCHF_LSJTR performs similar calculations for electric E1, E2,..., or magnetic M1, M2,...transitions between all LSJ states of two sets of expansions. Oscillator strengths, line strengths, transition energies, and transition probabilities are ...
