About the numerical solution of the Percus–Yevick equation in the critical region for nontruncated potentials

Abstract

Some problems related to the numerical solution of the Percus–Yevick equation in the critical region for a nontruncated potential are discussed. It is shown that the numerical method employed by the authors in a previous paper produces an abrupt decay of h(r) and an anticipation of the asymptotic behavior of c(r), when r tends to the cutoff distance R.
