In order to reduce the computational load in evaluating the two-electron relativistic integrals, the charge density is approximated by a linear combination of the squares of s-type spatial basis functions. Including the two-electron spin-orbit interaction effect is found to improve the calculation results. c 2006 American Institute of Physics., application/pdf}, pages = {164106-1--164106-4}, title = {Relativistic calclation of nuclear magnetic shielding tensor including two-lectron spin-orbit interaction interactions}, volume = {125}, year = {2006} }
