Data on Neutron Widths do not refute Random--Matrix Theory    [PDF]

J. F. Shriner Jr, H. A. Weidenmüller, G. E. Mitchell

Recent analyses of the distribution of reduced neutron widths in the Nuclear Data Ensemble (NDE) and in the Pt isotopes claim strong disagreement with predictions of random--matrix theory. Using numerical simulations we identify the causes for the apparent disagreement. For the NDE it is a strong bias inherent in the method of analysis. In the Pt isotopes, it is likely to be a threshold state.
