Energy Levels inF19from a Study of theO18(d, n)F19Reaction

A counter ratio investigation has been made of the ${\mathrm{O}}^{18}(d, n){\mathrm{F}}^{19}$ reaction, using oxygen targets enriched to 40 percent ${\mathrm{O}}^{18}$. A search was made for energy levels in ${\mathrm{F}}^{19}$ between excitation energies of 6.1 and 9.8 Mev. In this region, levels were found at 6.184 and 6.48 Mev. A resonance in the forward yield of neutrons from the deuteron bombardment of ${\mathrm{O}}^{18}$ was found at 1.64 Mev. The cross section for the ${\mathrm{O}}^{18}(d, n)$ reaction was measured by comparing the yield with that from the ${\mathrm{O}}^{16}(d, n)$ reaction, the cross section for which is known.
