Dear FLUKA experts,

We are interested in O-16(gamma, alpha)C-12 and N-14(gamma,p)C-13 reactions below 9MeV. We set up FLUKA models with thin targets and
"experimentally" determined the cross-sections. Sample input file and derived cross-sections are attached.

The model is simple: photon beam is incident on 1% radiation length target. Photon and e-/e+ production and transport thresholds are
set to 20 keV below the beam energy. Number of alphas is scored in the target region. This is repeated for beam energies between 7.2
and 9.2 MeV in 20 keV steps.

We would like to know:
1. If this is the best way to find out the cross-sections used by FLUKA;
2. If we determine that the cross-sections in FLUKA significantly differ from the experimental data, is there a way to run FLUKA
using our custom tabulated cross-sections.

Thank you in advance for your time.
