| 摘 要： | 通过重离子熔合蒸发反应142Nd(32S,1p3nγ)170Re布居了缺中子双奇核170Re的高自旋激发态,识别出了该核的一条转动带并建议了其组态为πh1/2 νi13/2。基于对同中子素能级系统性、旋称反转系统性、带内B(M1)/B(E2)、准粒子Routhians、动力学转动惯量和Total Routhian Surface(TRS)等带结构特征的详细分析和讨论,进一步确认了对A=170核区目前最缺中子双奇核高自旋转动带组态、宇称和自旋值的指定。

| Abstract: | One high-spin rotational band in neutron deficient odd-odd nucleus 170 Re has been identi-fied and assigned to the πh1/2 vi13/2 configuration through the 142Nd (32 S, 1 p3nγ)170 Re reaction. The band is analyzed on the basis of the arguments of energy systematics, signature inversion sys-tematics, intra-band B(M1)/B(E2) ratios, quasiparticle Routhians, dynamic moment of inertia and Total Routhian Surface(TRS) calculations. From detailed analyses on its structural proper-ties, the configuration, spins and parity have been further assigned for this rotational band. |
