Neutron scattering cross sections from /sup 14/N and /sup 9/Be at 11, 14, and 17 MeV

Neutron scattering cross sections were measured for /sup 14/N and /sup 9/Be at incident neutron energies of 11, 14, and 17 MeV using time-of-flight methods. Angular distributions for /sup 14/N and /sup 9/Be elastic scattering and /sup 9/Be inelastic scattering to the 2.429-MeV excited state were obtained betwee 20 and 160 deg in 5-deg increments. The data were corrected for finite geometry effects using a Monte Carlo simulation code. Lengendre polynomial coefficients deduced by fitting the experimental data are tabulated. The results of a spherical optical model analysis for the /sup 14/N data are reported. Coulomb correction terms are obtained from a comparison of neutron and proton elastic scattering data for /sup 14/N.
