1095242 095_Am_242 ENDF/B-VII.0 T. Kawano, M.B. Chadwick, A. Kahler, P.G. Young [Oct. 2010, Aug. 2011] MF=2 Resonance Parameters
ENDF/B-VII.0 resonance parameters (were from ENDF/B-VI)
were replaced by the JENDL-4 resonance parameters.
The energies of resolved resonances are almost identical
to the values in ENDF/B-VI, but spins and widths show
some differences.
In the unresolved resonance range, we adopted LSSF=1,
so that the dilute cross sections are now given in File 3.
MF=3 Neutron Cross Sections
MT=18
We performed a SOK analysis in the entire energy range to
obtain both the cross sections and its covariance.
The energy boundary was lowered to 150 eV. The subthreshold
cross sections are now given in File 3.
MT=102
The capture cross section was re-evaluated with the
Hauser-Feshbach calculations (CoH3), which reproduces
the DANCE experimental data and an integral measuremnt.
MF=32 Resonance Parameter Covariance
Take from JENDL-4, as for the resonance parameters.
MF=33 Neutron Cross Section Covariances
The covariance matrices for the total, inelastic, (n,2n),
(n,3n), (n,4n), and capture cross sections were calculated
with KALMAN, combining the statistical model calculations
with available experimental data. The covariance matrix for the fission cross section was obtained with the SOK code.
New evaluation + JENDL-3.3 At low incident neutron energies, the resonance parameters were
directly taken from the JENDL-3.3 evaluation file. The sections MF1,MT452,455,456 and MF5,MT18 were also adopted from
the JENDL-3.3 evaluation.
