Gamma-Rays from Fluorine Due to Proton Bombardment

Abstract

A detailed study has been made of the resonance excitation of gamma-rays from fluorine when bombarded with high speed protons in the energy range 0.18 Mev to 2.2 Mev. Because of improvements in the high voltage generator and in the preparation of uniform thin fluorine films, the resonance peaks obtained are much narrower than in the previous work at this laboratory, and many new resonances have been discovered. For the seven resonance peaks which are best defined, estimates are given as to voltage position and half-width.
