Abstract：
In this paper,based upon analysing the various factors which might cause the overbinding of ⁵He,we make a proper adjustment for the wave function of the core nucleus ⁴He.With the adjusted core wave function and various Λ-N interactions,we calculate the Λ-hyperon binding energy B_Λ(⁵He) of the ⁵He ground state and obtain a reasonable agreement between the theoretical and experimental values of B_Λ(⁵He).Thus, the ⁵He overbinding problem could be explained.
