Abstract

The method of evaluation outlined in a previous work has been utilized here to evaluate certain other three- electron and four- electron atomic integrals involving s Slater-type orbitals and exponential correlation with unlinked r_ij's. Limiting expressions for various such integrals have been derived, which has not been done earlier. Closed-form expressions for ,, , and have been obtained.
