Relativistic pair correlation energies of Xe were computed by employing a partial‐wave expansion up to order L mex = 5. The Dirac‐Fock ( DF ), SCF , and many‐body perturbation calculations were performed by employing analytic basis sets of well‐tempered GAUSSIAN‐type functions. A detailed study of the pair correlation energies in Xe is done in order to analyze the nature of relativistic and correlation effects in this heavy‐atom system. © 1992 John Wiley & Sons, Inc.
