Abstract
N. Bohr, R. Peierls and G. Placzek discuss the typical difference between nuclear reactions in the regions of discrete and continuous level distributions of the compound nucleus. The argument developed is used to clear up an apparent difficulty as regards the order of magnitude of the cross-sections of heavy nuclei for the photo-effect with ejection of neutrons.
