Light element standard cross sections for ENDF/B. Version IV

Technical Report ·
DOI:https://doi.org/10.2172/7329788· OSTI ID:7329788
; ;
Several light-element standard cross-section evaluations in the ENDF/B-IV file are described and compared with experimental measurements. The hydrogen scattering cross section has long been accepted as a standard since it is essentially equal to the total cross section which is well known and varies smoothly with incident neutron energy. The /sup 3/He(n,p)T, /sup 6/Li(n,t)..cap alpha.., /sup 10/B(n,..cap alpha../sub 0/)/sup 7/Li, and /sup 10/B(n,..cap alpha../sub 1/)/sup 7/Li*(478-keV ..gamma..) reactions have positive Q values and large thermal cross sections which make them ideal to use in neutron flux monitors. The Yale phase shifts were used to generate the hydrogen elastic scattering cross section and angular distributions while comprehensive R-matrix analyses were performed to determine the /sup 6/Li and /sup 10/B cross sections.
