DIFFERENTIAL CROSS-SECTIONS AT LOW ENERGIES FOR H-2(D,P)H-3 AND H-2(D,N)HE-3

We have measured differential cross sections for the H2(d,p)3H and H2(d,n)3He reactions at 11 deuteron bombarding energies from 20 to 117 keV. The differential data are accurate to 2.0% (relative) over most of the energy range, with an additional scale error of 1.3%. Integrated cross sections are derived with total errors generally about 1.5%. The results are compared with other measurements and with an existing R-matrix analysis. We find a larger D-wave reaction amplitude than previously reported. Formulas for the cross sections and reactivities are given. © 1990 The American Physical Society.
