Abstract

The structure of the neutron-rich odd-even nuclei ^{37, 39}          ₁₅P _22,24 and ^{43, 45}          ₁₇Cl _26,28 nuclei has been investigated through in-beam γ-ray spectroscopy using the fragmentation of a 60.3 A ^. MeV ⁴⁸Ca beam on a thin Be target. Level schemes as well as spin assignments are proposed for the nuclei studied in the present work. The experimental data are compared to shell model calculations and related to the onset of collectivity within the sd orbitals around N = 28.
