Shell-model calculations for 16ΛO and 17ΛO using microscopic effective interactions with Σ degrees of freedom
Abstract
Shell-model calculations in a large model space are performed for 16ΛO and 17ΛO. Effective interactions with degrees of freedom of Σ in addition to Λ and nucleons are derived from hyperon-nucleon and nucleon-nucleon interactions within the framework of the unitary-model-operator approach. Effects of the Σ degrees of freedom and the parity-mixing intershell coupling on the Λ hypernuclear structure are investigated, employing the Nijmegen NSC97a-f and NSC89 hyperon-nucleon potentials.
