Low Excited States of F19. III. Coulomb Excitation by α Particles

We have investigated the yield of gamma rays resulting from the bombardment of F19 by α particles [1]. Up to an α-particle energy 2.8 Mev we observed only the 1.28 Mev γ ray of the reaction F19(α,p)Ne22*, and the 114-kev and 200-kev radiations from the first and second excited states of F19 produced by inelastic scattering of the α particles. The γ rays were detected with a 1 1/2 in. X 1 1/2 in. sodium iodide scintillation spectrometer. The pulse spectrum was recorded with a 10-channel analyzer.
