The polarization ({ital P}) and the analyzing power ({ital A}) were measured for the {sup 48}Ca({ital p},{ital n}){sup 48}Sc reaction at 135 MeV. Of special interest is the difference ({ital P}{minus}{ital A}) in these two quantities for the transitions to the two 1{sup +} states at 2.52 and 16.8 MeV. Because of the difference in the predominant one-particle--one-hole configurations for these two states, viz., ({ital f}{sub 7/2},{ital f}{sub 7/2}{sup {minus}1}) and ({ital f}{sub 5/2},{ital f}{sub 7/2}{sup {minus}1}), respectively, qualitative differences in {ital P}{minus}{ital A} are predicted based on nonlocal exchange contributions. The experimental results agree qualitatively with these predicted differences, but there are significant quantitative differences indicating that other effects contribute as well.
