A program to compute isotope shifts in atomic spectra

Abstract
The energy of a level of a specific isotope is affected both by the nuclear motion and the nuclear volume. This program treats the resulting energy shift as a small perturbation that can be separated into the normal and specific mass shift and field shift. Given an electronic wave function, generated either by the MCHF program (LS format) or the MCHF_CI (LSJ format), isotope independent parameters are computed and, from these, shifts between isotopes are predicted.

Title of program: MCHF_ISOTOPE
Catalogue Id: ACLF_v1_0

Nature of problem
This program is a part of the MCHF atomic-structure package and allows for calculations of the isotope shift for bound-state systems, which is induced by the finite mass (mass shift) and the finite charge distribution (field shift) of the nucleus.
