 Given a macroscopic cross section of Σ = σρ, and a reaction rate of R = ΦΣ = Φσρ, the probability of interaction becomes Pdx = Njσ(Ei)dx = Σdx.Listed below are the cross sections of common atoms or alloys.Thermal Neutron Cross Sections (Barn)
Microstructural evolution is driven in the material by the accumulation of defects over a period of sustained radiation.
