The 62Ni(p,d)61Ni reaction has been studied with 65 MeV polarized protons. Angular distributions of the differential cross section and analyzing power have been measured for neutron hole states in 61Ni up to an excitation energy of 7 MeV. The data analysis with a standard distorted-wave Born approximation theory provides transferred angular momenta l and j and spectroscopic factors for several strongly excited states. The 1f7/2 hole state spreads largely in the excitation energy region of 2-6 MeV, while the 1f5/2, 2p3/2, and 2p1/2 hole states into only 2-4 levels. The strength function of the 1f7/2 hole state is analyzed with an asymmetrical Lorentzian function. The damping mechanism of the single hole states is discussed.
