The ($sup 3$He,d) reaction on Ni isotopes was studied at 30.2 MeV bombarding energy. Twenty-six unbound analog states in Cu isotopes were populated, and the observed differential cross sections are presented. Two different distorted-wave Born-approximation methods for stripping calculations to unbound analog states were used in the analysis. Proton spectroscopic factors were deduced and compared with published neutron spectroscopic factors for the parent states. The agreement is generally good, except for the pair of isotopes $sup 62$Ni-$sup 62$Cu. The different sensitivity to the transferred angular momentum of the corresponding (d,p) and ($sup 3$He,d) reactions is discussed. The present data are compared with the results of previous studies of the ($sup 3$He,d) reaction in the A approx. 90 mass region. It is concluded again that the ($sup 3$He,d) reaction to analog states is complementary to the (d,p) reaction for the study of levels in the parent states which are populated through large angular momentum transfers.
