Abstract：
The effective interaction between Λ and α is obtained by folding the Λ-N interaction to the nucleon density of the α particle, which gives the correct form factor of α particle in the high energy electron scattering experiment. Using this effective interaction, we calculate the binding energy of the doudle Λ in ⁶_ΛΛHe and the binding energy of Λ in ⁹_{Λ_^Λ}Be by means of the adiabatic approximation to the hyperspherical harmonic method. The results are satisfactory.
