【Abstract】 The relativistic corrections to the non-relativistic energies of the 1s~22p~2P states of Lithium-like atoms from Z=3 to 7 are calculated with the aid of irreducible tensor theory. Firstly, analytic expressions for the matrix elements of the relativistic Hamiltonian operators, such as mass correction term, one- and two- body Darwin interaction terms, spin-spin contact interaction term and orbit-orbit interaction term, are derived explicitly. Secondly, all the angular integrations and spin sum are calculated by using irreducible tensor theory and all the radial integrations are calculated by using hydrogen-like atom radial wave functions. Finally, the relativistic corrections energies are obtained and compared with experimental values. The differences between the calculated results and the experimental data are found to be less than 0.8%.更多还原
