Abstract
We present two versions of a program and the underlying algorithm, for the efficient calculation of integrals of the form Z(r1, r2) = integr al d3r3 p(r3) X(r1, r3) Y(r2, r3). The two versions differ in the amou nt of required memory. Such integrals appear in many calculations in p hysics and chemistry, specially when studying many-body problems of fi nite systems.
