Angular distributions of the vector analyzing power and the absolute cross section were measured for the 58 Ni(d, p) 59 Ni reaction at a deuteron energy of 10 MeV. The observed j -dependence of the vector analyzing power allowed unambiguous spin assignments for the following states in 59 Ni with excitation energies in MeV : 0.0, 3 2 − ; 0.341, 5 2 − ; 0.465, 1 2 − ; 0.879, 3 2 − ; 1.303, 1 2 − ; 1.686, 5 2 − ; 3.454, 3 2 − ; 3.858, 3 2 − ; 4.495, 5 2 + . The data are well reproduced by DWBA calculations employing deuteron and proton optical model parameters obtained from analyses of elastic scattering cross sections and polarizations. A tentative spin assignment of 9 2 + is made for the level at 3.061 MeV. A 5 2 + assignment to the level at 3.538 MeV is suggested on the basis of the empirical behavior of the j -dependence of the vector analyzing power for l = 2 transitions. Measurements of the vector analyzing power for the four low-lying 59 Ni states formed by l = 1 transfer were made for angles from 2.5° to 15° using a magnetic spectrograph. A very strong j -dependence was observed for these far-forward-angle measurements in agreement with DWBA predictions. |
