Behaviour of the $Λ$-separation energy ($B_Λ$) with two- and three- baryon potential strengths is thoroughly investigated. Solutions of the potential strengths giving experimental $B_Λ$ are presented.8 pages, 2 figuresNuclear TheoryBehaviour of the $ΛN$ and $ΛNN$ potential strengths in the $_Λ^5$He hypernucleustext
