A first γ -ray study of Cl47,49 spectroscopy was performed at the Radioactive Isotope Beam Factory with Ar50 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 Ar50 (p,2p) , a spin assignment could be determined for the low-lying states of Cl49 from the momentum distribution obtained with the SAMURAI spectrometer. A spin-parity Jπ=3/2+ is deduced for the ground state of Cl49 , similar to the recently studied N=32 isotope K51 . The evolution of the energy difference E (1/21+) -E (3/21+) is compared to state-of-the-art theoretical predictions.
