Is there incomplete mixing of states with different K quantum numbers in the neutron resonance region?

A recent publication claimed incomplete mixing of states with different K quantum numbers in the neutron resonance region. We discuss the theoretical implications of such a claim and show that it leads to serious discrepancies with the statistical model. We, therefore, reexamine the experimental data on which such a claim is based. The totality of the evidence invalidates the claim that K mixing in the resonance region is incomplete.
