Porter-Thomas fluctuations of neutron widths skew compound nuclear decay probabilities from their statistical Hauser-Feshbach values. We present a straightforward method to correct Hauser-Feshbach calculations for these fluctuations, useful for modeling near-threshold competition between gamma and neutron emission following beta decay or when standard width fluctuation corrections are inadequate.
