| 1083209 | 83-Bi-209 | JEFF-3.1 | NRG Eval Modifications for JEFF-3.2 from the JEFF-3.1 file - MF-2 is updated in MLBW, based on the parameters from Mutti PhD and, if no information, on the Atlas of Neutron Resonances, 5th edition. - MF-32 was added, based on uncertainties quoted in Mutti PhD and in the Atlas of Neutron Resonances. Uncertainties on the bound level were adjusted to reproduce experimental uncertainties. - MF-33 was added, based on Monte Carlo calculations from the TALYS and TASMAN codes. - The following values were obtained: Thermal capture cross section: 40.1 mb +/- 4.9 % Thermal elastic cross section: 9.29 b +/- 1.1 % Resonance Integral: 152 mb +/- 4 % - Details of the evaluation work (performed together with the Pb evaluation) is presented in a NIM/A paper, submitted in December 2007 |
