Abstract：
The ^9_ΛBe hypernucleus is considered as a α+Λ+α three-body system. With a saparable potential which includes only s-wave Λ-α interaction as the Λ-α effective interaction, the Schrödinger equation of the system is solved in the Born-Oppenheimer approximation. The two-center problem is solved first, and then the binding energy of ^9_ΛBe ground state is calculated. The calculated result is in good agreement with the experimental value.
