dc.description.abstractAn investigation was made of the electromagnetic disintegration of carbon, nitrogen, and oxygen leading to production of the unstable nuclei Be(7) and C(11). Targets of graphite, melamine, and water were bombarded with 75-MeV electrons from the Naval Postgraduate School linear accelerator. The disintegration fragments of interest were counted by detecting their decay activity, Be(7) by the 477-Kev gamma ray from its daughter nucleus and C(11) by the 511-Kev photons from the annihilation of its emitted positron. Electron and photon effects were separated by interposing an additional radiator for one bombardment of a given type of target, then repeating with a similar target without the radiator. Radioactive fragments of Be(7) and C(11) were found in all bombardments; N(13) was also found in bombardments of melamine and water. Electrodisintegration cross sections for processes yielding C(11) were found to range from 17.5 microbarns for carbon down to 0.3 microbarns for oxygen. The corresponding values for processes yielding Be(7) ranged from 1.3 microbams to 0.14 microbarns. Integrated photodisintegration cross sections were found to be approximately 50 times greater than these.en_US
