MCHF method, normal mass shift, spesific mass shift, field shift.Abstract
Isotope shift effects including mass shift and field shift on the levels for the levels of 3P0,1,2, 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.
