Resonant Capture of Protons by Fluorine in the Energy Range 0.5 to 2.2 Mev

The energy of a proton beam from a pressurized electrostatic generator was measured absolutely by means of an electrostatic analyzer, and used to irradiate thin targets containing fluorine. The γ-ray yield was observed as a function of proton energy and the energies for resonant proton capture were determined to an accuracy of one part in a thousand in most cases. The width of each resonance at half-maximum yield was also measured.
