Dear FLUKA experts,

I am calculating stopping powers for protons by simulating the energy deposited by a single proton in a thin layer of water (using USRBIN by region). I am simulating this for each proton energy in the NIST spreadsheets. I want to compare the results obtained with this method with the values from the DELTARAY output and from NIST. For proton energies higher than 1 MeV, this method works perfectly and the results have very small differences when compared to the values from the output or from NIST. However, for low energies, the results show large discrepancies (see figure). How can I correct this? Please find attached the input file I am using to simulate this problem.

Thank you all in advance.
Kind regards,
