Measurement of recoil proton polarizations in the electrodisintegration ofdeuterium by polarized electrons

In order to test modem theories of two-nucleon bound and scattering states, we have measured the spin polarization of ejectile protons in the electrod isintegration reaction d((e) over right arrow, e'(p) over right arrow)n. Co mpared with spin-averaged observations, these observables offer the potenti al of enhanced sensitivity to details of the reaction process. The experime nt was carried out in quasielastic kinematics (q(mu)q(mu)= -2m(p) omega= -0 .38GeV(2)/c(2)). Protons were detected at two angles corresponding to neutr on recoil momenta p(r) of 0 and 100MeV/c. Full nonrelativistic calculations of the polarization transfer components s(l) and s(t), including leading o rder relativistic contributions, describe our measurements well, but calcul ations of the induced polarization s(n) at p(r) = 100 MeV/c underpredict th e experimental result.
