Abstract

Effects of the Σ\SigmaN channels on the spin-orbit force in Λ\Lambda-hypernuclei are investigated. It is found that the cancellation between the symmetric and the antisymmetric Λ\LambdaN spin-orbit force becomes more complete when the contribution from the Σ\SigmaN channels is included. This may be the one of the reasons why the observed LS splitting of the Λ\Lambda single particle energy is very small.
