Polarization transfer in quasifree (p→ ,n→) reactions on ²H and ^3,4He targets at 197 MeV

In this paper, we present a complete set of polarization-transfer observables measured at 197 MeV in the quasifree region for (p→,n→) reactions on 2H and 3,4He targets. Data were obtained at laboratory scattering angles of 13°, 24°, 37°, and 48° for the 2H target and at 13° and 37° for the 3,4He targets. The data span an energy-loss range up to 150 MeV, with a corresponding momentum-transfer range q50.75-2.4 fm-1. The polarization-transfer observables are used to calculate the center-of-mass polarization observables. The empirical results for the 2H target are compared to the observables obtained from the free nucleon-nucleon database and with Faddeev-type calculations. No discernible differences are observed in either the values of polarization-transfer observables or in the center-of-mass polarization observables among the three nuclei studied in this paper.
