Isotope shift effects on the ground-state levels for neutral tin

Abstract

Isotope shift effects including mass shift and field shift on the levels for the levels of ³P_0,1,2, ¹D₂ and ¹S₀ for 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 has been used. The calculation of isotope effects for tin has been here performed firstly although there are some works on the atomic structure of tin. The results including isotope shift effects on the levels have been discussed, and new energy values have been compared other available works in literature.
