In this work, we have compared neutron energy spectrum measured by nuclear photo emulsion method in the “Energy plus Transmutation” collaboration in the Joint Institute for Nuclear Research, Russia to that produced by simulations using Geant4 toolkait and evaluated the agreement between theoretical and experimental results when bombarding the Pb/U setup with 1.5 GeV-energy protons. We used high energy Bertini, Binary, and Liege models in the toolkit for the simulations. For energy range of 3-25.3 MeV, the numbers of neutrons that entered and produced in the photoemulsion volume were 2954, 2075, and 1799 for Bertini, Binary, and Liege, respectively. The coincidence between the neutron energy spectra of simulation and experiment was very good.
