Abstract
The correlation between nuclear deformation and the resonance width of photonuclear reactions is discussed. The general trend of the nuclear deformation is in good agreement with the predictions of Marumori, Suekane, and Yamamoto, and the existence of the correlation is clarified. The calculation assuming the splitting of the resonance and a constant width for spherical nuclei agrees qualitatively with experiments, but quantitatively the calculated values are too low, especially for strongly deformed nuclei. For light nuclei the quantative calculation has little meaning, but a similar correlation is found for them. The mass-number dependence of the resonance width is discussed qualitatively; it turns out that the variation of this width arises from various causes and is not a simple function of mass number. A discussion of the nuclear shape in the highly excited state (∼20 Mev) is given, and it is shown that this nuclear shape may not be very different from the shape in the ground state.Keywords
