A study of N15(n,d) C14 and N15(n, t) C13 ground state reactions as functions of energy and angle in the neutron energy range 13.6 to 14.8 MeV
Abstract
Techniques were developed for producing neutron spectra having the characteristics needed for excitation function measurements. A method was also developed for measuring the neutron spectrum incident on a reaction target. The N15 reaction data were taken with a counter telescope which consisted of two gas differential energy detectors plus a scintillator. Excitation functions were measured at counter angle settings of 0 deg and 45 deg over the neutron energy range 13.6 through 14.8 MeV. Cross section angular distributions were taken at En = 14.1 and 14.6 MeV. At forward angles the 14.1 MeV sigma(theta) for N15(n, d)C14 g.s., disagrees with a previously reported measurement. The direct mechanism was found to be completely dominant for the (n,d)reaction. A DWBA analysis gives a fairly good fit to the shape of the observed angular distribution for N15(n,d)C14 g.s., but predicts an energy dependence different from that observed.
