ris3: A program for relativistic isotope shift calculations

Abstract An atomic spectral line is characteristic of the element producing the spectrum. The line also depends on the isotope. The program ris3 (Relativistic Isotope Shift) calculates the electron density at the origin and the normal and specific mass shift parameters. Combining these electronic quantities with available nuclear data, isotope-dependent energy level shifts are determined. Title of program: RIS3 Catalogue Id: ADEK_v2_0 Nature of problem Prediction of level and transition isotope shifts in atoms using four-component relativistic wave functions.
