研究目的
Comparing simulations of photo-nuclear reactions using Monte Carlo codes PHITS and FLUKA with experimental data at the SPring-8 injector for 250MeV and 961MeV electrons.
研究成果
The simulations using FLUKA and PHITS show reasonably good agreement with the experimental data within about ±50%. The data are useful for estimating photon and neutron energy distributions, though discrepancies in high energy regions indicate areas for future improvement.
研究不足
Large statistical errors for some detectors, discrepancies in simulation results for high energy regions, need for future investigations to improve statistical errors and simulation accuracy.
