The result of GEANT4 simulation of neutron photoproduction on deuterium and oxygen-16 is presented below:

Neutron yield ([math]4\pi[/math]) from [math]D_2O[/math] (90%[math]D_2[/math] concentration) in reaction [math]O16(\gamma,n)O15[/math]. 410 neutrons initially produced got absorbed in the target (E=0MeV) and 2509 neutrons will likely escape the target:

Neutron yield ([math]4\pi[/math]) from [math]D_2O[/math] (90%[math]D_2[/math] concentration) in reaction [math]D_2(\gamma,n)p[/math]. 857 neutrons initially produced got absorbed in the target (E=0MeV) and 17656 neutrons will likely escape the target:
