Abstract

A complete set of polarization-transfer observables has been measured at 197 MeV in the quasifree region for the $(\vec{p}, \vec{n})$ 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.
