Abstract
From the experimental results of Jackson & Coulombe (1974) and Vetter (1970) in the arc spectrum of xenon, the isotope shifts of 30 levels in the low configurations 5p$^{5}$6s, 5p$^{5}$6p,5p$^{5}$5d and 5p$^{5}$7p are obtained, for the mass numbers 136, 134, 132, 130 and 128. A parametric study of these shifts for each isotope is made, with 3 parameters for the even levels and 6 for the odd levels. Following the conclusions of Jackson & Coulombe (1974), the respective contributions of mass-and field-effects to the shifts of the levels and to the parameters are evaluated from King diagrams. The ab initio values obtained for the parameters through the Hartree-Fock non-relativistic and relativistic methods show a satisfactory agreement with the experimental values.Keywords
