Effect of NN and ΛN tensor forces on Λ-separation energy of sub(Λ)sup(5)He

  • 1. Hokkaido Univ., Sapporo (Japan). Dept. of Physics

Description

The sub(Λ)sup(5)He wave function is solved variationally with a realistic NN potential and a ΛN potential including a tensor force. The NN and ΛN tensor forces reduce the Λ-separation energy B sub(Λ) for sub(Λ)sup(5)He by about 2.0 and 1.6 MeV, respectively. The B sub( lambd )-value calculated here is 2.4 MeV and is not larger than the experimental one. A main part of the overbinding problem in sub(Λ)sup(5)He is resolved by introducing the NN and ΛN tensor forces. (author)
