The neutron-rich nucleus $$^{50}$$Ar is produced by the fragmentation reactions of $$^{54}$$Ca, $$^{55}$$Sc, and $$^{56}$$Ti at the RIBF facility in RIKEN, and its deexcited $$gamma$$ rays are observed for the first time. The first $$2^+$$ level in $$^{50}$$Ar is identified to lie at 1178(18)keV from the most intense $$gamma$$-ray spectra. This experimental data, together with the systematics of the $$2^+$$ levels for surrounding nuclei, is analyzed with large-scale shell-model calculations. Consequently, the $$N=32$$ sub-shell gap in $$^{50}$$Ar is equivalent to that of $$^{52}$$Ca, thus making the $$2^+$$ level in $$^{50}$$Ar higher than that of $$^{48}$$Ar. The shell-model calculation also predicts that the $$N=34$$ sub-shell gap enhances in going from Ca to Ar, which will be verified by forthcoming experiments for $$^{52}$$Ar.
