A complete set of polarization-transfer observables has been measured at 197 MeV in the quasifree region for the (p→,n→) reactions on C, Ca, and Pb targets. Data have been obtained at laboratory scattering angles of 13°, 24°, 37°, and 48°, which span an energy-loss range up to 150 MeV, with a corresponding momentum-transfer range q=0.75–2.4 fm-1. The empirical results are compared to the observables obtained from the free nucleon-nucleon data base. Derived spin-longitudinal and spin-transverse responses for Ca are compared with those previously obtained at 346 and 495 MeV incident energies.
