Spin-parity measurements in the neutron-rich N ∼ 20 34P and 36S nuclei

摘要: Yrast and near-yrast energy levels in the neutron-rich N ∼ 20 nuclei 34P, 36S were populated using transfer/deep-inelastic processes following 34S + 115In reaction at an incident of 140MeV. The use a multi-clover array has facilitated polarization measurements observed γ-rays necessitated some changes previously known level scheme. observation negative-parity these on periphery “island inversion” is indicative influence intruder orbitals structure low spins. Shell-model calculations indicate that inclusion from upper pf shell important even for low-lying positive-parity states.
