Inelastic neutron scattering: resonances and fluctuations

Abstract

R-function theory of Thomas used in study of inelastic scattering of neutrons to a definite state. Onset of fluctuations, effects of randomness of phases of interfering amplitudes, and variations in statistical distributions of neutron widths considered in detail. Fluctuations exhibit well-defined maxima and sharp minima. For certain adjacent resonances, strong interference effects are predicted.
