A first γ -ray study of 47,49Cl spectroscopy was performed at the Radioactive Isotope Beam Factory with 50Ar projectiles at 217 MeV/nucleon, impinging on the liquid hydrogen target of the MINOS device. Prompt deexcitation γ rays were measured with the NaI(Tl) array DALI2+. Through the one-proton knockout reaction 50Ar(p, 2p), a spin assignment could be determined for the low-lying states of 49Cl from the momentum distribution obtained with the SAMURAI spectrometer. A spin-parity Jπ = 3/2+ is deduced for the ground state of 49Cl, similar to the recently studied N = 32 isotope 51K. The evolution of the energy difference E(1/2+ 1 ) − E(3/2+ 1 ) is compared to state-of-the-art theoretical predictions. |
