文摘We investigate a Σ-mixing probability of a neutron-rich Λ-hypernucleus 10ΛLi by using microscopic shell-model calculations considering a Λ-Σ coupling in the first order perturbation. The theoretical Σ-mixing probability in 10ΛLi is found to be about 0.48%,due to the appearance of multi-configuration Σ Nuclear excited states which can be strongly coupled with the Λ ground state in 10ΛLi.
