Adopting the separability assumption in conjunction with the hypernetted-chain approximation and the minimum principle of Helmholtz free energy based on the trial density matrix expressed in terms of Jastrow-type wave functions, a set of coupled Euler-Lagrange equations are obtained for the radial d
