概要

• 論文の詳細を見る

• The _Λ^5He wave function is solved variationally with a realistic NN potential and a ΛN potential including a tensor force. The NN and ΛN tensor force reduce the Λ-separation energy B_Λ for _Λ^5He by about 2.0 and 1.6MeV, respectively. The B_Λ-value calculated here is 2.4 MeV and is not larger than the experimental one. A main part of the overbinding problem in _Λ^5He is resolved by introducing the NN and ΛN tensor farces.
