CORRECTIONS TO HARTREE-FOCK APPROXIMATION FOR HOMOGENEOUS NUCLEAR MATTER

The convergence of a modified Goldstone linked-cluster expansion for the binding energy of nuclear matter is considered for the Tabakin and Elliott-Flowers potentials. It is argued that a comparison of the first-order term with the second-order term cannot give a direct indication of the convergence of the series. Calculations have therefore been performed to evaluate all terms through third order. For the Elliott-Flowers potential the third-order terms amount to 26% of the second-order contribution; for the Tabakin potential they are less than about 10%. © 1969 The American Physical Society.
