Photodisintegration of 16O and 63Cu by Photons of Variable Energy

Abstract

Proton capture reactions in light nuclei provide ?-radiation with energy controllable by variation of proton energy. The radiation from proton capture by 7Li has been used to investigate the (?,n) reactions in 16O and 63Cu over an energy range of 300 keV around 17·7 MeV. No resonant behaviour was observed in 16O. A variation in the 63Cu photoneutron cross section is interpreted as the combined effect of many unresolved levels.
