ISOTOPE SHIFT EFFECTS ON THE GROUND-STATE LEVELS FOR NEUTRAL TIN

Abstract

otope shift effects including mass shift and field shift on the levels for the levels of 3P0,1,2, 1D2and 1S0for the ground-state configuration of the neutral tin (Sn I, Z= 50) have been investigated. In calculations, the multiconfiguration Hartree-Fock method within the frame work of Breit-Pauli Hamiltonian hasbeen used. The calculation of isotope effects for tin hasbeen here performed firstly although there are some works on the atomic structure of tin. The results including isotope shifteffects on the levels havebeen discussed, and new energy values have been compared other available works in literature.
