Double differential neutron emission cross sections of /sup 10/B and /sup 11/B at 6, 10 and 14 MeV and of /sup 6/Li, /sup 7/Li and /sup 12/C at 14 MeV

Double differential neutron emission cross sections of /sup 10/B and /sup 11/B at 6, 10 and 14 MeV and of /sup 6/Li, /sup 7/Li and /sup 12/C at 14 MeV [electronic resource]

Neutron emission spectra of /sup 10/B and /sup 11/B were measured at 6, 10, and 14.1 MeV and those of /sup 6/Li, /sup 7/Li and carbon at 14.1 MeV using time-of-flight technique. Absolute double differential cross sections were obtained by using scattering from hydrogen as a cross section reference....

Description
Summary:Neutron emission spectra of /sup 10/B and /sup 11/B were measured at 6, 10, and 14.1 MeV and those of /sup 6/Li, /sup 7/Li and carbon at 14.1 MeV using time-of-flight technique. 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-IV) of the Monte Carlo correction for multiple scattering. In particular, the library for /sup 11/B appears to be very unrealistic, with a total elastic cross section at 14.1 MeV which should be higher by 50%
