Using a split-pole magnetic spectrograph, the /sup 45/Sc(..cap alpha.., d)/sup 47/Ti reaction was studied at E (..cap alpha..) =25 MeV and with a range of angles from 7degree to 50degree. These measurements are compared with results we obtained using the /sup 45/Sc(/sup 3/He, p)/sup 47/Ti reaction. One result of this comparison is the identification of candidates for states with high spin. The major emphasis of this paper is the study of such states. Two-particle spectroscopic amplitudes are calculated using an (f/sub 7///sub 2/)/sup 7/ model, assuming an inert /sup 40/Ca core. Zero-range distorted-wave Born-approximation calculations are then performed with these amplitudes. A comparison between these shell-model calculations and the experimental results indicates that the states at 4.506 and 3.583 MeV have J/sup pi/'s of 19/2/sup -/ and 17/2/sup -/. A second result of the comparison between the (..cap alpha.., d) and (/sup 3/He, p) reactions concerns the nature of the 3.22-MeV state in /sup 47/Ti. It is strongly populated with an orbital angular momentum transfer of 0 by the (/sup 3/He, p) reaction and only weakly populated by the (..cap alpha.., d) reaction, suggesting that it is formed by the transfer of a neutron-proton pair with S=0, T=1. This is similar to the transfer forming the state at 7.346 MeV, the analog of the /sup 47/Sc ground state. (AIP)
