Title: Analytic evaluation of some three- and four- electron atomic integrals involving s STO's and exponential correlation with unlinked $r_{ij}$'s,
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 $<r_{12} r_{13} /
r_{14}>$, $<r_{12}r_{34}/r_{23}>$, $<r_{12}r_{23}/r_{34}>$,
$<r_{12}r_{13}/r_{34}>$ and $<r_{12}r_{34}/r_{13}>$ have been obtained.
