✦ Synopsis

I n part I of this paper the ,:luster integral of second order for quantum plasmas was given by a definite integral over the SLATERSUm of two particles. Here this integral is calculated exactly, using the method of perturbation theory with respect to the interaction parameter e2 for the orders eZk with k < 3, and the method of scattering phase shifts for the orders e"'with k > 4. The cluster int,egral of second order is expremed by quantum virial functions and exchange virial functions. These functions are expressed in form of integrals over the complex energy plane. From these integrals TAYLOR expansions and asymptotic representations of the virial functions are derived. In the case of lower temperatures, the semiclassical forinulae derived by LARKIN and the author are obtained, using the first terms of the asymptotic representation.
