Hydrogen fusion-energy reactions

Abstract
At the Los Alamos Ion Beam Facility we have installed a low-energy fusion cross section (LEFCS) apparatus specifically designed to measure cross sections to high accuracy for the various fusion-energy reactions among the hydrogen isotopes in the bombarding-energy range 10 to 120 keV. To date, we have completed and published our study of the D(t,α)n reaction, have finished data-taking for the D(d,p)T and D(d, 3He)n reactions, and have nearly finished data-taking for the T(t,α)nn reaction. Here we describe the LEFCS facility, present final and preliminary results for these reactions, and compare them with R-matrix calculations.
