Περίληψη:
In order to test modem theories of two-nucleon bound and scattering
states, we have measured the spin polarization of ejectile protons in
the electrodisintegration reaction d((e) over right arrow, e’(p) over
right arrow)n. Compared with spin-averaged observations, these
observables offer the potential of enhanced sensitivity to details of
the reaction process. The experiment 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 neutron recoil momenta p(r) of 0
and 100MeV/c. Full nonrelativistic calculations of the polarization
transfer components s(l) and s(t), including leading order relativistic
contributions, describe our measurements well, but calculations of the
induced polarization s(n) at p(r) = 100 MeV/c underpredict the
experimental result. (C) 1999 Published by Elsevier Science B.V. All
