# Do deviations of neutron scattering widths distribution from the Porter-Thomas law indicate on failure of the Random Matrix theory?

## TL;DR

This paper investigates whether deviations from the Porter-Thomas law in neutron scattering widths suggest failures in the Random Matrix theory, by calculating these deviations within an extended random matrix framework.

## Contribution

It extends the random matrix approach to account for resonance overlapping and calculates the resulting deviations from the Porter-Thomas law.

## Key findings

- Deviations are quantitatively characterized.
- Resonance overlapping impacts the width distribution.
- Implications for the validity of Random Matrix theory.

## Abstract

Deviations of neutron scattering width distributions from the Porter-Thomas law due to resonances overlapping are calculated in the extended framework of the random matrix approach.
