In this paper, we present a complete set of polarization-transfer observables measured at 197 MeV in the quasifree region for $(\overrightarrow{p},\overrightarrow{n})$ reactions on ${}^2\mathrm{H}$ and ${}^{3,4}\mathrm{He}$ targets. Data were obtained at laboratory scattering angles of $13°,$ $24°,$ $37°,$ and $48°$ for the ${}^2\mathrm{H}$ target and at $13°$ and $37°$ for the ${}^{3,4}\mathrm{He}$ targets. The data span an energy-loss range up to 150 MeV, with a corresponding momentum-transfer range $q=0.75\mathrm{}–2.4\hspace{0.5em}{\mathrm{fm}}^{-1}.$ 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.
