    Notes: Abstract The reaction54Xe(n, α)52Te was investigated in the neutron energy range 12.5 to 18.0 MeV. A high pressure gas scintillator filled either with pure xenon of natural isotopic abundance or with a mixture of xenon and helium was used as a target and as a detector simultaneously. The helium served as a monitor, (n, α)-spectra were measured and analyzed by evaporation theory. Large components of direct processes were found. The level density parameter of52Te was determined as (17.0±1.7) MeV−1. The cross section excitation function is given as well as the branching ratios for evaporation and direct processes as a function of neutron energy.

    Notes: Abstract High-accuracy analyzing-powerA y(θ) data forn-d elastic scattering at 12 MeV have been measured using the polarized-neutron facilities at the Triangle Universities Nuclear Laboratory (TUNL). The present data have been combined with our previousn-d measurements at 10, 12, and 14.1 MeV to form the highest-accuracyA y(θ) data set forn-d elastic scattering below 20 MeV. These data are compared to recent Faddeev-based neutron-deuteron (n-d) calculations which use the Paris and Bonn equivalent separable potentials PEST and BEST, as well as Doleschall's representation of theP- andD-wave nucleon-nucleon interactions. None of these models adequately describe the data in the angular region around the maximum ofA y(θ). Possible reasons for the discrepancies are discussed. The sensitivity of the present Faddeev-based calculations to various angular momentum components of the nucleon-nucleon interaction are examined.
