The combined analytical relations in terms of these basic functions are derived for the non- and quasi-relativistic atomic integrals over integer and noninteger n-Slater-type orbitals. The relationships obtained are valid for the arbitrary values of principal quantum numbers and screening constants of Slater orbitals.eninfo:eu-repo/semantics/closedAccessSlater-type orbitalsnonrelativistic atomic integralsquasirelativistic atomic integralsnoninteger principal quantum numbers.Article81475610.1142/S0219633609004393Q3WOS:0002658282000032-s2.0-65249146584N/A
