摘要
The energy of the first excited state in the neutron-rich N=28 nucleus Cl-45 has been established via in-beam gamma-ray spectroscopy following proton removal. This energy value completes the systematics of the E(1/2(1)(+))-E(3/2(1)(+)) level spacing in odd-mass K, Cl, and P isotopes for N=20-28. The results are discussed in the framework of shell-model calculations in the sd-fp model space. The contribution of the central, spin-orbit, and tensor components is discussed from a calculation based on a proton single-hole spectrum from G-matrix and pi+rho meson exchange potentials. A composite model for the proton 0d(3/2)-1s(1/2) single-particle energy shift is presented.
