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。One high-spin rotational band in neutron deficient odd-odd nucleus 170Re has been identified and assigned to the πh1/2νi13/2 configuration through the ^142Nd（^32S,1p3nγ）^170Re reaction. The band is analyzed on the basis of the arguments of energy systematics, signature inversion systematics, 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 properties, the configuration, spins and parity have been further assigned for this rotational band.
