Show affiliationsThe photodisintegration processes splitting the nuclei 126C and 168O completely into alpha-particles have been studied in some detail by the photographic plate method. It is found that, for energies below about 25 MeV resonances occur in the excitation functions, indicating that a compound nucleus interpretation may be valid. These results, and also certain data of Green and Gibson concerning the inelastic scattering of neutrons in carbon, are related to excited states of the nuclei 126C and 84Be as intermediate stages in the various processes. Levels in 126C at 9.6 MeV and 11.3 ± 0.3 MeV occur and these yield first an alpha-particle and 84Be in the ground state, while a third level in 126C near 12 MeV is found to yield 84Be in the broad 3 MeV excited state. Other levels in 84Be at 4.1 MeV and 17 MeV, disintegrating into two alpha-particles, are found as intermediate stages in these reactions.
