Abstract：
A detailed comparison between the Hartree-Fock (HF) and the mass operator (M) potential is made by means of a solvable three-level model. It is found that in a quite large region of force parameters (FPR) the M potential gives a much better result than the HF potential and at certain points in FPR the HF result undergoes a sudden jump while the M result varies smoothly. The convergence behavior of the perturbation expansion of M has also been studied.
