【摘要】 通过束流能量为166MeV的重离子熔合蒸发反应142Nd(32S,1p3nγ)170Re,用在束γ谱学方法研究了170Re的高自旋激发态,首次建立了双奇核170Re的转动带能级纲图.发现该转动带与A=170核区双奇核中πh11/2(?)vi13/2组态带的旋称劈裂特征及规律相符.
【Abstract】 High-spin states in doubly odd 170Re have been populated and investigated using 142Nd (32S, 1p3nγ) 170Re reaction at 166MeV bombarding energy. One rotational band in 170Re has been identified for the first time in the present study. The band has been assigned to be built onthe πh11/2 ■vi13/2 configuration according to their quasiparticle alignment, signature splitting,level spacing systematics, as well as the existing knowledge in neighboring nuclei. The result extends the high-spin studies of A=170 odd-odd nuclei to the currently lightest rhenium isotope.
