We present measurements of differential cross sections and the analyzing powers Ay, iT11, T20, T21, and T22 at Ec.m. = 431.3 keV. In addition, an excitation function of iT11(θc.m. = 87.8• ) for 431.3 ≤ Ec.m. ≤ 2000 keV is presented. These data are compared to calculations employing realistic nucleon-nucleon interactions, both with and without three-nucleon forces. Excellent agreement with the tensor analyzing powers and cross section is found, while the Ay and iT11 data are found to be underpredicted by the calculations.13.75. Cs,21.45.+v,24.70.+s,

Angular distributions of cross sections and complete sets of analyzing powers for the 3 He(d ជ ,p) 4 He reaction have been measured at five energies between E d ϭ60 and 641 keV. The energy dependence of the cross section was also measured from 245 to 685 keV, and the absolute cross section was determined at E d ϭ426 keV. The data have been included in an R-matrix analysis of the 5 Li system. The bare-nuclear cross section derived from the R-matrix parametrization was used to determine the electron screening potential.
