Double differential cross section in Fluka

AI Thread Summary
To calculate the double differential cross section for iron at 90 degrees and 22 MeV in Fluka, adjustments in the input and output files are necessary. The user is utilizing the usryield card for this calculation but suspects incorrect modifications in the input file. Guidance is sought on the specific changes needed to accurately obtain double differential cross section values in mbarn/MeV/sr. The goal is to compare these calculated values with experimental data from EXFOR. Expert assistance is requested to ensure proper configuration for the desired output.

Double differential cross section in Fluka
Dear experts, I would like to do a double differential cross section calculation for iron at 90 degrees and at 22 MeV in Fluka. What changes should I make in the input and output files of the application and what transformations should I make in order to see the double differential cross section values in mbarn/mev/sr. I want to compare these values with the values in the exfor experiment data.I used the usryield card from Fluka to do this calculation.I think I may have made some adjustments in the input file incorrectly and I would like to get help from you experts on this subject

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
