The suggested approach guarantees a highly accurate calculation of the S(alpha*)-SFOIs for the arbitrary values of parameters and locations of orbitals.eninfo:eu-repo/semantics/closedAccessMultielectron Molecular IntegralsMulticenter IntegralsQuantum-MechanicsRecurrence RelationsDisplaced CenterExpansionCoefficientsCoulombOriginSetsArticle87561461610.1246/bcsj.20130307Q2WOS:0003360112000052-s2.0-84901045173Q2
