We measured the spin observables A{sub y}, P, and S{sub NN{sup {prime}}} for the {sup 208}Pb(p,n){sup 208}Bi reaction at 135 MeV at laboratory angles of 0{degree}, 3{degree}, 6{degree}, and 9{degree}. The overall energy resolution was about 1 MeV. Data for S{sub NN{sup {prime}}} are compared with distorted-wave impulse-approximation calculations that use random-phase approximation wave functions. Comparisons are also made for the {sup 48}Ca(p,n){sup 48}Sc reaction. The agreement between these calculations and the data is generally good, after adjustment of the nucleon-nucleon interaction in the random-phase approximation calculations to place the 0{sup +} isobaric-analog states at the correct excitation energies. A single adjustment of the nucleon-nucleon force works for both target nuclei. {copyright} {ital 1997} {ital The American Physical Society}
