Frank W. K. Firk
TL;DR
This paper applies R-function theory to analyze inelastic neutron scattering, focusing on resonance behaviors, fluctuations, interference effects, and the statistical distribution of neutron widths, revealing complex fluctuation patterns and resonance interactions.
Contribution
It introduces a detailed analysis of neutron scattering resonances using R-function theory, highlighting the effects of phase randomness and interference on fluctuations.
Findings
Fluctuations show well-defined maxima and minima.
Strong interference effects occur between adjacent resonances.
Statistical distributions of neutron widths are characterized in detail.
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.
