Abstract
Following a previous paper on the 3d series, specific-mass isotope shifts are computed, by means of the non-relativistic Hartree-Fock method, in atoms of the 4d, 4f, 5d and 5f series, in the alkalis and in a few two- and three-electron spectra. In heavy atoms, when isotopic measurements of muonic X-ray transition lines are available, direct comparisons with experiment are presented for optical transitions with large specific shifts. In the other cases, through the use of King diagrams, the comparison is made between the Hartree-Fock (HF) and experimental values of some known linear combination of the specific shifts of two lines. In all nlN long series, the HF and experimental values agree within a factor of two. This gives confidence in the main HF result, i. e. the prediction that the lines with the jump of an nl electron have by far the largest mass shifts
