Abstract：
In this paper, a ∧-N effective interaction of Volkov type is introduced with Har-tree-Fock method in multi-center shell model. The results for binding energies of ¹³Cand ⁹Be are satisfactory. Comparing with the effective potentials which are mentionedas results of fitting the data of 1-p s-wave scattering, the p component in ∧-N interac-tion is weaker than s-component by 1/3 at least. Moreover, majorana force is impor-tent but model-dependent.
