Anomalous fluctuations of s-wave reduced neutron widths of $^{192,194}$Pt resonances
arXiv:1007.3675 · doi:10.1103/PhysRevLett.105.072502
Abstract
We obtained an unprecedentedly large number of s-wave neutron widths through R-matrix analysis of neutron cross-section measurements on enriched Pt samples. Careful analysis of these data rejects the validity of the Porter-Thomas distribution with a statistical significance of at least 99.997%.
