Abstract：
In this paper the nuclear structure of hypernucleus ₅^ΛHe and its effect on the binding energy B_Λ of A hyperon are systematically studied. The Polarization effect of the core a is explored. The binding energy B_Λ of ₅^ΛHe including D-state mixing component is calculated. The results show that the core α suffers a serious distortion by the interaction with Λ hyperon and has no longer the structure of a free Alpha Particle. The D-state mixing can improve the B_Λ calculated value about 0.5MeV. A Possible three cluster structure is further explored. The Λ+d+d model can give a B_Λ value close to the experimental one. The further exploration is necessary.
