Low-lying structure of $$^{50}$$Ar and the $$N$$=32 subshell closure

https://doi.org/10.1103/PhysRevLett.114.252501
 Times Cited Count：51 Percentile：88.03(Physics, Multidisciplinary)

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.

Nuclidic mass formula on a spherical basis with an improved even-odd term

Koura, Hiroyuki; Tachibana, Takahiro*; Uno, Masahiro*; Yamada, Masami*

https://doi.org/10.1143/PTP.113.305
 Times Cited Count：435 Percentile：99.21(Physics, Multidisciplinary)

A nuclidic mass formula composed of a gross term, an even-odd term and a shell term is presented as a revised version of the mass formula constructed by the present authors and published in 2000. The gross term has almost the same functional form as in the previous formula, but the parameter values in it are somewhat different. The even-odd term is treated more carefully, and a considerable improvement is brought about. The shell term is exactly the same as the previous one; it was obtained using spherical single-particle potentials and by treating the deformed nucleus as a superposition of spherical nuclei. The new mass formula is applicable to nuclei with ${it Z}$ $$>$$ 1 and ${it N}$ $$>$$ 1. The root-mean-square deviation from experimental masses is 0.658 MeV, which is less than that of the previous mass formula, 0.680 MeV.
