Abstract

The level structure of 165Ho has been studied by means of the 166Er(t, α)165Ho, 164Dy(α, t)165Ho, and 164Dy(3He, d)165Ho reactions using magnetic spectrographs and photographic emulsions. The results were interpreted on the basis of the Nilsson model with pairing and Coriolis mixing effects included. Experimental nuclear structure factors were obtained and compared with calculated results. Previously identified bands based on the 72[523], 32[411], 12[411], 72[404], and 52[413] Nilsson orbitals were observed. The previously suggested 12[541] band was confirmed and levels up to spin 92 were assigned. The 112 member of the 92[514] band was also identified. States assigned earlier as the spin 52 and 72 members of the 52[532] band were reassigned to the 52[402] orbital. New evidence is presented which indicates that the previously assigned 52[413] band is actually the (K0+2) γ-vibration based on the 12[411] state, with a large admixture (≈ 50%) of the 52[413] single-particle configuration.
