Extreme non-statistical effects in γ decay of 95Mo neutron resonances
Abstract
We obtained unprecedentedly large sets of total radiation widths Γγ of 95Mo neutron resonances for all six s- and p-wave Jπ values. We demonstrate that the resulting Γγ distributions can be used to test and improve nuclear models. In particular, Γγ distribution simulations in the framework of the nuclear statistical model yielded results in sharp disagreement with the data. Simulations modified to include doorway effects resulted in much better agreement. These results call into question the reliability of the nuclear statistical model, and demonstrate that high-quality Γγ data are a virtually untapped resource for testing and improving nuclear models.
