1048116 048_Cd_116 New evaluation + ENDF/B-VII.0 The remaining part of the evaluation (above the RRR) is the ENDF/B-VII.0 file, which description has been left below intact (including the description of the replaced RRR evaluation in
order to be temporarily used for comparison).
ENDF/B-VI MOD 4 Revision (R.Q. Wright, ORNL, V. McLane, NNDC,
August 1996)
. Added file 1 comments
. Unresolved resonance parameters were revised in order to
eliminate a discontinuity in total cross section at 100 keV.
. The s- and p-wave strength functions are increased to
0.2E-4 and 3.4E-4, respectively.
. The scattering radius is increased to 6.50 fm. This revised
value is used for both the resolved and the unresolved
resonance regions.
The calculated resolved resonance thermal scattering cross
section is 5.806 barns, in good agreement with the experimental
value, 6 +/- 1. The revised evaluation has higher total and
elastic cross sections between 9 and 100 keV but the capture is
almost identical to the previous evaluation. The differences
vary from +1.2 to -2.0%, relative to the previous capture in
the ENDF/B-VI, release 2, evaluation.
