摘要：

The intensities of transitions from neutron-resonance states in Er169 and Hf178 to low-lying states with spin 25 are shown to depend on the K values of the final states. This K dependence favors a conclusion that the resonance states can also be associated with good K quantum numbers. The results contradicts the hypothesis that K is completely mixed in this energy region, as expected for a chaotic structure. © 1990 The American Physical Society.
