  "abstract": "Neutron-unbound states in $^ {50}$Ar and $^ {52}$Ar were investigated via the (p,2p) proton-knockout reaction using the invariant-mass spectroscopy technique. Two ($^ {50}$Ar) and three ($^ {52}$Ar) distinct, narrow resonances were observed in the vicinity of the neutron separation energy. Based on a comparison with theoretical level schemes and calculated (p,2p) cross sections, tentative spin-parity assignments have been proposed. The good degree of consistency between the predicted level structures and the observed states indicates that the large $N$ = 32 and $N$ = 34 shell gaps inherent in the theoretical calculations accurately describe the nuclear structure in this region. These results provide further support for the robustness of these subshell closures in the neutron-rich argon isotopes.",
