被引用回数:4 パーセンタイル:54.40(Physics, Nuclear)Excited states in S were investigated by in-beam -ray spectroscopy using the Mg(O, 21) fusion-evaporation reaction. The de-exciting -rays were measured with germanium detector arrays along with the measurement of evaporated charged particles in a segmented Si detector array. The level scheme was extended up to 12470 keV. The obtained level structure is compared with the large-scale shell-model calculations. The possibility of isoscalar-pair excited states is discussed for states with comparison between the experimental and theoretical results.

The high-spin states in S were investigated at Tandem-ALTO facility in Institut de Physique Nuclaire d'Orsay The Mg(O, 21n)S fusion evaporation reaction was used to populate high-spin states in S. The germanium -ray detector array ORGAM was employed to measure rays from high-spin states and charged particles evaporated from the compound nuclei were detected by a segmented silicon detector, Si-Ball. A level scheme for S was deduced based on the gamma-gamma-coincidence analysis and -ray angular correlation analysis. The half-life of the transition in the superdeformed band was estimated by measuring the residual Doppler shift. The deduced half-life shows the large collectivity of the band.
