  A first gamma-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
de-excitation gamma-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 J = 3/2+ is deduced for
the ground state of 49Cl, similar to the recently studied N = 32 isotope 51K.
