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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
