Core excitations up to E/sub x/ = 4 MeV in /sup 63/Cu have been studied by the reactions /sup 63/Cu(p,p')/sup 63/Cu and /sup 65/Cu(p,t)/sup 63/Cu at 40 MeV proton energy. The transferred angular momentum L has been determined for each transition on the basis of the angular distribution shape. A quartet-plus-doublet pattern is consistently observed for the groups of states corresponding to the 2/sup +//sub 1/, 3/sup -//sub 1/, and 4/sup +//sub 1/ states of the core nucleus /sup 62/Ni. This implies the existence of doublets arising from the coupling of collective states of the core with the 2p/sub 1/2/ proton orbital, in addition to the quartets from the coupling with the 2p/sub 3/2/ proton orbital considered in the conventional weak-coupling excited-core model. It is pointed out that the existence of a weak-coupling situation cannot be proved only on the basis of transfer-reaction data, and in this regard the importance of a comparative study of the inelastic-scattering and transfer-reaction data is emphasized.
