Abstract / Description:High-spin states in 160,161,162Ho have been populated in the reactions 158,160Gd(7Li, xn) at 56 MeV. In all three isotopes the known rotational bands have been extended to significantly higher spin. In 160 Ho, the band crossing in the 7/2-[523] 11/2-[505] band has been observed for the first time. The sequences built on the proton 7/2-[523], 7/2 + [404], 1/2 + [411] and 1/2-[541] states in 161Ho have been extended up to spin 51/2-, 35/2 + , 51/2 + and 41/2-, respectively, leading to the first observation of upbends in all four cases. In addition, a new band most probably belonging to this nucleus has been identified. In the most neutron-rich isotope 162Ho, the only known rotational band, which is built on the 7/2-[523] 5/2 + [642] configuration, has been extended up to the 28- state. The properties of all observed bands are discussed and compared to the neighbouring isotopes.
