Data from: Forward modeling approach to nuclear reaction cross sections: Applications in neutron inelastic scattering

The development of nuclear reaction models for the production of evaluated
nuclear data has traditionally been performed by comparing measured cross
sections with predictions from reaction model codes whose physical input
parameters are adjusted to obtain the best agreement between measured and
modeled results. To more directly probe reaction model inputs, this work
introduces a forward modeling approach to experimental reaction
cross-section determination, where the most important physical input
parameters to reaction model calculations are obtained via χ 2
minimization between measured and calculated observables. This was
demonstrated using data collected by the Gamma Energy Neutron Energy
Spectrometer for Inelastic Scattering (GENESIS) at the 88-inch cyclotron
at Lawrence Berkeley National Laboratory, a detection array consisting of
organic liquid scintillators and high-purity germanium (HPGe) detectors.
Using a broad-spectrum neutron beam and a 99.98%- enriched 56 Fe target,
GENESIS was used to perform a simultaneous measurement of 56 Fe γ -ray
production cross sections and secondary neutron energy and angle
distributions. The results of the forward modeling and inverse approaches
for gamma-ray production are included here. For secondary neutron energy
and angle distributions, the results of the forward model are included.
Also included are a set of best fit TALYS parameters and correlation
matrix representing between the TALYS parameters.
