Description
Angular distributions for the 163Dy(t,p) and 177Hf(t,p) reactions were measured using 17 MeV tritons from the McMaster University Tandem Van de Graaff accelerator. Reaction products were analyzed with a magnetic spectrograph and detected with photographic emulsions. Favored L=0 transitions confirmed assignments of the 5/2-[523] band in 165Dy and 7/2-[514] band in 179Hf. Additional L=0 transitions in each nuclide identified previously unknown 5/2- levels in 165Dy and 7/2- ones in 179Hf. Overall trends of L=0 strengths support the existence of subshell closures at neutron numbers 98 and 108. On the basis of a relatively strong L=2 transition, the Kπ=11/2- γ-vibration based on the 7/2-[514] state is identified at 1689 keV in 179Hf, about 440 keV above its previously-assigned Kπ=3/2- partner
