We compute the effective interaction at long wavelength of two opposite-spin 3He in superfluid 4He to second order in 3HeJHe mass difference perturbation theory. The correction to the Bardeen, Baym, Pines result V(0) = -~2m4s2/n 4, in second order, is expressed exactly in terms of the dependence of
