ris4: A program for relativistic isotope shift calculations

Published: 27 Sep 2018 | Version 1 | DOI: 10.17632/8vjpf69zch.1

Description of this data

Spectral lines from different isotopes display a small separation in energy, commonly referred to as the line isotope shift. The program RIS 4 (Relativistic Isotope Shift) calculates normal and specific mass shift parameters as well as field shift electronic factors from relativistic multiconfiguration Dirac-Hartree–Fock wave functions. These quantities, together with available nuclear data, determine isotope-dependent energy shifts. Using a reformulation of the field shift, it is possible to study, in a model-independent way, the atomic energy shifts arising from changes in nuclear charge distributions, e.g. deformations.
