Hi
Running your input file I obtained the attached spectrum for the scoring volume at zero degree. There is a peak in the energy bin comprises between 198.6 MeV and 196.7 MeV which is consistent with the kinematic of the reaction on Li 7.
With the binning structure you have chosen for scoring you cannot conclude on the peak broadness, I suggest to change the USRTRACK card to score the energy spectrum with a better resolution in your region of interest.
Greetings
Joachim

Hi
It is a little complicated to interpret your questions without the input file and corresponding result file. For a proper investigation it is required (where are you scoring your USRTRACK for example ? ….)
Best regards

Dear FLUKA usres,
I'm transporting neutrons from Li(p,n)Be reaction using USRTRACK with 200MeV proton beam and 8mm Li thickness. My problem is that the the peak fro quasi-monoenegetic neutrons is not at the maximum energy of the proton beam and on top of that its broad.
Since I don't know the physics model that was used to carry out the outcomes of the reaction I'm even struggling with discussing these other peaks which I though they result from the excitation of Li.
Any help will be valuable
Regards
N.R Mantengu
