(p,d) reaction on ⁶²Ni at 65 MeV

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 1f_7/2 hole state spreads largely in the excitation energy region of 2-6 MeV, while the 1f_5/2, 2p_3/2, and 2p_1/2 hole states into only 2-4 levels. The strength function of the 1f_7/2 hole state is analyzed with an asymmetrical Lorentzian function. The damping mechanism of the single hole states is discussed.
