Measurements have been maie of seven polarization transfer coefficients for the /sup 3/He(d,p)/sup 4/He reaction. The experiment used a polarized- deuteron beam from the Los Alamos Scientific Laboratory lamb-shift polarized-ion source, a liquid-nitrogen cooled /sup 3/He gas target, a magnetic quadrupole triplet for focusing the reaction protons, and a helium-filled polarimeter for simultaneously measuring the proton polarization along both transverse axes. Measurementa were made of the polarization transfer coefficients K/sup y'//sub y/ and K/sup x'//sub yz/ at theta = 0 deg for 4- to 14-MeV deuterons. A comparison of the K/sup y'//sub y/ results with the values reported for the /sup 3/H(d, n)/sup 4/He reaction over the same energy range sho ws good agreement, as would be expected for the two charge-symanctric reactions. In addition, we have measured the proton polarization P/sup y'/; the vector transfer coefficients K/ sup y'//sub y/, K/sup x'//sub z,/ and K/sup x'//s ub z/; and the tensor transfer and K/sup y'//sub xz/ at 8.0 MeV for laboratory angles of 15, 30, 45, and 60 deg . Calculated values for these observables from an R-matrix parametrization of the five-nucleon system are in good agreement with the data. (auth)
