Abstract
- In this paper, we present a complete set of polarization-transfer observables measured at 197 MeV in the quasifree region for $(\stackrel{\ensuremath{\rightarrow}}{p},\stackrel{\ensuremath{\rightarrow}}{n})$ reactions on ${}^{2}\mathrm{H}$ and ${}^{3,4}\mathrm{He}$ targets. Data were obtained at laboratory scattering angles of $13\ifmmode^\circ\else\textdegree\fi{},$ $24\ifmmode^\circ\else\textdegree\fi{},$ $37\ifmmode^\circ\else\textdegree\fi{},$ and $48\ifmmode^\circ\else\textdegree\fi{}$ for the ${}^{2}\mathrm{H}$ target and at $13\ifmmode^\circ\else\textdegree\fi{}$ and $37\ifmmode^\circ\else\textdegree\fi{}$ for the ${}^{3,4}\mathrm{He}$ targets. The data span an energy-loss range up to 150 MeV, with a corresponding momentum-transfer range $q=0.75--2.4 {\mathrm{fm}}^{\ensuremath{-}1}.$ The polarization-transfer observables are used to calculate the center-of-mass polarization observables. The empirical results for the ${}^{2}\mathrm{H}$ 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.
