The {sup 45}Sc({ital p},{ital n}){sup 45}Ti reaction was studied at 135 MeV with a beam-swinger system. Neutron kinetic energies were measured by the time-of-flight technique, with neutron detectors located in three detector stations at 0{degree}, 24{degree}, and 45{degree} with respect to the undeflected beam. Flight paths of 131.0, 131.1, and 81.3 m were used. The overall timing resolution was about 825 ps, providing energy resolutions of 320 keV in the first two stations and 520 keV in the third. The wide-angle spectra are dominated by a complex at {ital E}{sub {ital x}}=4.3 MeV. The angular distribution for this complex is fitted well by a distorted-wave impulse approximation calculation for an assumed {ital J}{sup {pi}}=17/2{sup {minus}},19/2{sup {minus}} ({pi}{ital f}{sub 7/2}{sup 2},{nu}{ital f}{sub 7/2}{sup {minus}1}) doublet. The spectra and angular distribution are consistent with ({ital p},{pi}{sup {minus}}) excitations of the same states and are in good agreement with a full 1{ital f}-2{ital p} shell-model calculation. The 17/2{sup {minus}},19/2{sup {minus}} strength predicted by distorted-wave impulse approximation calculations using these shell-model wave functions is in good agreement with the experimental measurements.
