Polarization transfer in quasifree p-vector,n-vector reactions on C, Ca, and Pb targets at 197 MeV

A complete set of polarization-transfer observables has been measured at 197 MeV in the quasifree region for the (p(vector sign),n(vector sign)) reactions on C, Ca, and Pb targets. Data have been obtained at laboratory scattering angles of 13 deg., 24 deg., 37 deg., and 48 deg., 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
