Behaviour of the ΛN and ΛNN potential strengths in the 5ΛHe hypernucleus

Study of He-5(Lambda) is presented using a realistic Hamiltonian and a fully correlated wavefunction including Lambda N space-exchange correlations. Behaviour of Lambda-separation energy (B-Lambda) with two- and three-baryon potential strengths is investigated. Solutions for these potential strengths giving experimental B-Lambda are presented.
