PHOTOPROTONS FROM FLUORINE
The results of a study of the ( gamma ,p) reaction in F/sup 19/ are presented. Thin foils of teflon were irradiated with bremsstrahlung of 15.5 and 19 Mev maximum energy. The photoprotons were recorded by nuclear emulsions. Each irradiation gives a proton spectrum containing well-resolved peaks. The peaks in the low-energy spectrum correspond to transitions from excited states in F/sup 19/ to the ground state in O/sup 18/. The information about these transitions was then then used to analyze the high-energy spectrum. The proton spectrum at the high-energy irradiation is interpreted as transitions from resonances in F/sup 19/ to the ground state and excited states in O/sup 18/. The observed fine structure in the ( gamma ,p) absorption was compared with measurements of ( gamma ,n); the agreement was found to be quite satisfactory. The angular distribution of the protons was measured and gave further information about the photon-absorption process. (auth)
