摘要：

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