Mo-99 Production
The above report suggests that
1.) you get about [math]\displaystyle{ 10^{12} \frac{neutrons}{s \cdot kW} }[/math] when a 30 MeV electron beam hits a converter like Tungsten producing photons which hit a 5 cm thick Moly target. A 100 kW electron beam could make about 800 Ci/s of Mo-99.
2.) The [math]\displaystyle{ ^{100}Mo(\gamma, f) }[/math] X-sect peaks at 160 mbarns when the photon energy is 15 MeV:(photofission of Mo-100 and U-238 have similar X-sections)
3.) single neutron emissions makes up about 60% of the photofission X-section [math]\displaystyle{ \Rightarrow }[/math] [math]\displaystyle{ ^{100}Mo(\gamma, n) }[/math] X-sect is about 96 mbarns when photon energy is 15 MeV
