THE PRODUCTION OF Be7, C11, N13 OR O15 FROM CARBON, NITROGEN, AND OXYGEN BY 87-MEV ELECTRONS.
Abstract
Targets of graphite, melamine and water were bombarded with 87-MeV electrons from the Naval Postgraduate School linear accelerator in order to investigate the production of the unstable nuclei Be7, C11, N13, or O15 from the electromagnetic disintegration of carbon, nitrogen and oxygen. The Be7 fragments were detected by observing the 477-KeV gamma ray from the daughter nucleus Li7. The other disintegration fragments were detected by the annihilation of the emitted positrons which produced 511-KeV photons. A copper radiator was introduced in one-half of the bombardments of each type of nucleus in order to separate the electron and photon effects. (Author)
