Invariant Imbedding and Neutron Transport Theory III-Neutron-Neutron Collision Processes [PDF]
Indiana University Mathematics Journal, 1959 Abstract : The effects on criticality of neutron-neutron collisions involving annihilation are investigated for one-dimensional, single and multi-group cases. The analytic treatment shows that regardless of the magnitude of the cross section for collision between moving neutrons, there is no critical length (mass).
