We present measurements of the polarization-transfer components in the $^2$H$(vec e,evec p)$ reaction, covering a previously unexplored kinematic region with large positive (anti-parallel) missing momentum, $p_{rm miss}$, up to 220 MeV$/c$, and $Q^2=0.65$ $({rm GeV}/c)^2$. These measurements, performed at the Mainz Microtron (MAMI), were motivated by theoretical calculations which predict small final-state interaction (FSI) effects in these kinematics, making them favorable for searching for medium modifications of bound nucleons in nuclei. We find in this kinematic region that the measured polarization-transfer components $P_x$ and $P_z$ and their ratio agree with the theoretical calculations, which use free-proton form factors. Using this, we establish upper limits on possible medium effects that modify the bound protons form factor ratio $G_E/G_M$ at the level of a few percent. We also compare the measured polarization-transfer components and their ratio for $^2$H to those of a free (moving) proton. We find that the universal behavior of $^2$H, $^4$He and $^{12}$C in the double ratio $frac{(P_x/P_z)^A}{(P_x/P_z)^{^1rm H}}$ is maintained in the positive missing-momentum region.
We report the first measurements of the transverse ($P_{x}$ and $P_{y}$) and longitudinal ($P_{z}$) components of the polarization transfer to a bound proton in the deuteron via the $^{2}mathrm{H}(vec{e},evec{p})$ reaction, over a wide range of missi
We report measurements of the induced polarization $vec P$ of protons knocked out from $^2$H and $^{12}$C via the $A(e,evec p,)$ reaction. We have studied the dependence of $vec P$ on two kinematic variables: the missing momentum $p_{rm miss}$ and th
We report the measurements of the transverse ($Px$) and longitudinal ($Pz$) components of the polarization transfer to a bound proton in carbon via the quasi-free $^{12}{rm C}(vec e,evec p)$ reaction, over a wide range of missing momenta. We determin
A comparison between polarization-transfer to a bound proton in quasi-free kinematics by the A$(vec{e},evec p)$ knockout reaction and that in elastic scattering off a free proton can provide information on the characteristics of the bound proton. In
Possible differences between free and bound protons may be observed in the ratio of polarization-transfer components, $P_x/P_z$. We report the measurement of $P_x/P_z$, in the $^2textrm{H}(vec{e},e^{prime}vec{p})n$ reaction at low and high missing mo
