The final expressions are obtained in closed form as a combination of Bessel functions. We discuss the notion of the\n ``2k_F'' oscillations and show that they occur as the far asymptote of our expressions. We show the existence of the intermediate asymptote of the interaction which is of the sign-reversal antiferromagnetic type and is the only term surviving in the limit of exact nesting.
