Radiative Proton Capture byO18

Abstract

A search for gamma-emitting levels in ${\mathrm{F}}^{19}$ between 8.3 and 9.8 Mev of excitation energy has been made by bombarding a NiO target (39% ${\mathrm{O}}^{18}$) with protons over the energy range 360 to 1960 kev. Resonances in the gamma-ray yield were observed with the use of a 3-in. diam×3-in. sodium iodide crystal and a 20-channel pulse-height analyzer. The results are as follows: The angular distribution of the 6.27-Mev gamma ray from the 1169-kev resonance was measured, and the results are listed in tabular form. The results of the present experiment are compared with other experiments using the ${\mathrm{O}}^{18}(p, \gamma ){\mathrm{F}}^{19}$, ${\mathrm{O}}^{18}(p, \alpha ){\mathrm{N}}^{15}$, and the ${\mathrm{O}}^{18}(d, n){\mathrm{F}}^{19}$ reactions.
