ABS>Angular distributions of the polarization of /sup 3/He(d,p)/sup 4/He protons were measured for unpolarized deuterons with laboratory energies of 1.99, 2.81, 3.94 and 6.00 MeV. The polarizations were determined from the left-right asymmetry of elastic scattering through 60 deg in /sup 4/He gas using a vaned polarimeter whose analyzing power was computed by trajectory tracing from the known p- polarizations. A contour diagram of proton polarization for deuteron energies of 1 to 12 MeV is presented. A Legendre polynomial expansion of four or five terms was fitted to the products p( THETA ) sigma ( THETA ). The coefficients of the expansions of these and other measurements show resonance- like behavior at /sup 5/Li excitations of 20.0 and 20.5 MeV. The vector- polarized beam and polarized-target analyzing powers are compared with the proton polarization. The proton polarizations are in good agreement with the /sup 3/ He(d,n)/sup 4/He neutron polarizations when compared at the same entrance-channel energy but disagree when compared at equal exit-channel energies or compound- nucleus excitations.
