| Popis: | The thermal-neutron flux produced by a $sup 252$Cf spontaneous fission neutron source was computed for various spherical assemblies with moderators of iron, aluminum, carbon, D$sub 2$O, beryllium, and H$sub 2$O and reflectors of H$sub 2$O and carbon. Consideration of spherical assemblies with a $sup 252$Cf source located at the center and at various distances from the center lead to a configuration, adaptable to neutron radiography, that has a small thermalization factor and a flat thermal-neutron flux. |
