Production of Low-Energy Gamma Rays by Neutron Interactions with Fluorine for Incident Neutron Energies Between 0.1 and 20 MeV

Differential cross sections for the production of low-energy gamma rays (<240 keV) by neutron interactions in fluorine have been measured for neutron energies between 0.1 and 20 MeV. The Oak Ridge Electron Linear Accelerator was used as the neutron source; incident neutron energies were determined by time-of-flight techniques. Gamma rays were detected at 92 deg using an intrinsic high-resolution germanium detector. Results are presented for the production cross sections of three gamma rays having energies of 96, 110, and 197 keV. These data are compared with previous experimental data; the agreement varies between poor and good.
