摘要
High-spin states in doubly odd Re-170 have been populated and investigated using Nd-142 (S-32, 1p3ngamma) Re-170 reaction at 166MeV bombarding energy. X-gamma and gamma-gamma-t coincidence measurements have been carried out in the experiment. Based on the coincidence relationships, a rotational band in Re-170 has been identified for the first time, extending the high-spin studies of A : 160 odd-odd nuclei to the currently lightest rhenium isotope. The band has been assigned to be built on the pih(11/2)circle times vi(13/2) configuration according to their rotational properties in quasiparticle alignment, signature splitting, level spacing systematics, as well as the existing knowledge in neighboring nuclei. Low-spin signature inversion has been suggested for the pih(11/2) circle times vi(13/2) band in Re-170.
