The final results are especially useful for the computations of arbitrary multicenter multielectron integrals that arise in the Hartree-Fock-Roothaan (HFR) approximation and also in the correlated methods based upon the use of STOs as basis functions.eninfo:eu-repo/semantics/openAccessslater type orbitalscorrelated interaction potentialsone-range addition theoremsmulticenter multielectron integralsUnsymmetrical and symmetrical one-range addition theorems for slater type orbitals and Coulomb-Yukawa-like correlated interaction potentials of integer and noninteger indicesArticle7225726210.1142/S0219633608003691Q3WOS:0002549529000072-s2.0-43949119119N/A
