The energy-corrected transition rates for [gamma] decay of the [ital n]-capture states in [sup 168]Er and [sup 178]Hf are calculated from data available in the literature. If one assumes that the capture states have good [ital K] values, the data reveal a significantly lower average transition rate when the normal [ital K]-selection rules are broken than for [ital K]-allowed transitions. The effect is more profound in the data from thermal neutron capture than in the data from 2 keV neutron capture.
