Cross Sections for Neutron Production from 6- and 10-MeV Neutrons Incident on ¹⁰B and ¹¹B

Using time-of-flight techniques, we have measured neutron emission spectra from 6- and 10-MeV incident neutron energies on ¹⁰B and ¹¹B for laboratory angles between 20 and 145 deg using the unique neutron source reaction ¹H(t,n). Double-differential cross sections and their integrated values have been extracted for elastic and inelastic processes, and their integrated values are summarized. In cases where discrete scattering peaks could be analyzed, differential cross-section angular distributions have been extracted and are compared to other results and to evaluated nuclear data.
