The $\hat{I}›$-$\hat{I}\pounds$ coupling effect in the neutron-rich $\hat{I}›$-hypernucleus ${}_{\hat{I}}{›}^{10}$Li by microscopic shell model

Abstract

We investigate the structure of the neutron-rich $\hat{I}›$-hypernucleus ${}_{\hat{I}}{›}^{10}$Li by using microscopic shell-model calculations considering a $\hat{I}›$-$\hat{I}\pounds$ coupling effect. The calculated $\hat{I}\pounds$-mixing probability in the ${}_{\hat{I}}{›}^{10}$Li ground state is found to be about 0.34 % which is coherently enhanced by the $\hat{I}›$-$\hat{I}\pounds$ coupling configurations, leading to the energy shift 0.28 MeV which is about 3 times larger than that in ${}_{\hat{I}}{›}^7$Li. The importance of the $\hat{I}\pounds$ configuration obtained by the $\hat{I}\pounds N$ interaction and the potentiality of the neutron-rich environment are discussed.
