Abstract:

Using a three-baryon

\Lambda NN

potential having a spin-independent dispersive and a two-pion exchange components, realistic variational Monte Carlo calculations have been performed for the

\Lambda

-seperation energy for

~{5}_{\Lambda}

He. A relationship between strengths associated with both pieces of

\Lambda NN

force giving exact experimental

\Lambda

-seperation energy has been obtained which then combined with our previous study on

~{17}_{\,\,\Lambda}

O hypernucleus determines a unique and acceptable set of strength parameters for

\Lambda NN

potential. The

\Lambda NN

force is found important for the core polarization.
