| 英文摘要 | High-spin states of the neutron-rich odd nuclei Dy-159,Dy-161,Dy-163 have been studied using the incomplete fusion reactions Gd-158,Gd-160(Li-7,(p,d,t)xn). In Dy-159, the band crossing in the 11/2(-)[505] band has been observed for the first time. Moreover, 11 E1 transitions connecting both signatures of the 3/2(-)[521] band to the 5/2(+)[642] band have been observed in this nucleus; the deduced B(E1)/B(E2) ratios as well as the B(M1)/B(E2) ratios for transitions within the 3/2(-)[521] band show a pronounced signature dependence. In Dy-161 and Dy-163, rotational bands have been extended to significantly higher spin values. In Dy-161, the sequences built on the neutron 5/2(-)[523] and 3/2(-)[521] states have been followed up to spin 49/2(-) and 33/2(-), respectively, and in both cases upbends have been observed around (h) over bar omegaapproximate to0.26 MeV. In addition, a new band most probably built on the 11/2(-)[505] single-particle state has been identified in this isotope. In Dy-163, both the 5/2(-)[523] ground state band and the structure built on the 5/2(+)[642] neutron orbit have been extended up to the 45/2(-) and 49/2(+) states, respectively. However, no band crossing has been observed in this nucleus. The properties of the observed bands in Dy-159,Dy-161,Dy-163 are discussed and compared to calculations performed within the projected shell model. |
