Description

Abstract We present two versions of a program and the underlying algorithm, for the efficient calculation of integrals of the form Z(r_1 , r_2 )=∫d^3 r_3p(r_3 ) X(r_1 , r_3 ) Y(r_2 , r_3 ). The two versions dif fer in the amount of required memory. Such integrals appear in many calculations in physics and chemistry, specially when studying many-body problems of finite systems. Title of program: CONVUS - HIGH ENERGY Catalogue Id: ACNJ_v1_0 Nature of problem Problems in physics, chemistry, applied mathematics as well as in other fields, are often in need of an efficient 3-D convolution quadrature. Versions of this program held in the CPC repository in Mendeley Data acnj_v1_0; CONVUS - HIGH ENERGY; 10.1016/0010-4655(93)90122-S This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
