The total electronic density at the nucleus for atoms has been calculated by the Xα method with ab initio exchange parameter αSCF. Calculations have been done for a few atoms with the exchange parameter 2/3, 1 and αHF, too. It has been found that the values obtained with αHF and αSCF show the best agreement with the Hartree-Fock data.
