using LOW-BIAS, indeed you get rid of neutrons with energy < 20 MeV, and
therefore the only fissions you score are
those from high energy hadrons. But why do you want to do that, when it is
possible to obtain both at the same time, using LE-FISSION and HE-FISSION?
The cutoff energy for the LE/HE is 20 MeV, of course.

Hi all,

500 MeV protons on UO2 target encased inside Ta container.

Isolate low energy (<=3D 20 MeV) neutron contribution to fission product
yields from hight energy protons and neutrons.

1- Can I achieve the above objective by using LOW-BIAS to set the energy
cutoff for low energy neutrons. I am only setting the ECut WHAT(1):

LOW-BIAS 1. 0.0 rUO2Tgt

2- I am looking at the LE-FISSION and HE-FISSION densities via the SCORE
estimator; however, I do not know what the cut off energy is for the
LE/HE. I could not find it in the manual.

Thank you in advance,
