Abstract
Abstract Neutron emission spectra of 10B and 11B were measured at 6, 10 and 14.1 MeV and those of 6Li, 7Li. and carbon at 14.1 MeV using time-of-flight techniques. Absolute double differential cross sections were obtained by using scattering from hydrogen as a cross section reference. Integration over energy ranges and solid angle yielded integrated elastic and total neutron emission cross sections. At 6 and 10 MeV excellent agreement with total cross section data is found; at 14.1 MeV the new data tend to be higher than expected. The biggest error source in the continuous spectra stems from uncertainties in the input library (ENDF/B-V) of the Monte Carlo correction for multiple scattering. In particular, the library for 11B appears to be very unrealistic, with a total elastic cross section at 14.1 MeV which should be higher by 50%.
