1003006 | 003_Li_006 | ENDF/B-VII | MODIFICATION OF ENDF/B-VII EVALUATION FOR NEW DATA G. M. Hale (3/9/09) Results of new R-matrix analysis that included absolute WNR measurements of the 6Li(n,t)4He differential cross section made in 2008 were used for MF=3, MT=105 above the standards range (0.94 <= E <= 4) MeV. In the range (4 <= E <= 8) MeV, the (n,t) cross section was obtained from Legendre fits to the new WNR data, matched smoothly to the previous cross section above 8 MeV. The differences with the previous (n,t) cross section above about 1 MeV were distributed between the elastic (MT=2) and inelastic (MT=58) cross sections, so that the same total cross section was preserved. |
ENDF/B-VI | 1. MF=1,MT=451 - Comments were added regarding estimated (expanded) covariance for the Standards Cross Sections. 2. MF=3,MT=53 - LF flag and Q-value corrected. |
MODIFICATION OF ENDF/B-VI EVALUATION FOR ENDF/B-VII G. M. Hale and P. G. Young (4/12/06) 1. Standard cross sections for MT=105 from the ENDF/B-VII international standards analysis were incorporated below 2.8 MeV. The previous evaluation (ENDF/B-VI) was smoothed slightly between 2.8-3.4 MeV for a smooth join of the data. 2. MF=4, MT=2 elastic angular distributions from the ENDF/B-VII R-Matrix analysis were added below 2.8 MeV. 3. MF=6, MT=105 angular distributions were added from the ENDF/B-VII R-Matrix analysis below 2.8 MeV. 4. MF=33, MT=105 data from the ENDF/B-VII international standards analysis were incorporated into the evaluation. |
