220 neutron capture Gamma rays of Dy 165 were measured with the Risø curved crystal spectrometer. The intense transitions permitted the construction of a level scheme for this oddN nucleus. The rotational bandsK=7/2+,K=1/2− andK=5/2− were precisely localized, including the spin 11/2 states. Gammavibrational bands built on these Nilsson orbits were observed with their band heads at 538.6, 573.5 and 570.2 keV. TheI=5/2 term at 533 keV can be considered as the 5/2− Nilsson state. The branching ratios allowed the determination of (g K−gR)2-factors for the ,  and  bands and yieldedE 1-hindrance factors.
