抄録

Gaussian Expansion Method has been applied to four-body calculations of ⁴ _Λ H and ⁴ _Λ He, and four-body calculation of ⁴He tetramer. We found that Λ N- Σ N coupling is important to make bound A = 4 hypernuclei. The binding energies of the tetramer ground state and excited states are obtained as 558. 98 and 127. 33 mK.
