Nuclear Structure ofF18

The nuclear structure of ${\mathrm{F}}^{18}$ was studied with the reactions ${\mathrm{O}}^{17}({\mathrm{He}}^3, d){\mathrm{F}}^{18}$, ${\mathrm{O}}^{16}({\mathrm{He}}^3, p){\mathrm{F}}^{18}$, and ${\mathrm{Ne}}^{20}(d, \alpha ){\mathrm{F}}^{18}$ induced with 15-MeV ${\mathrm{He}}^3$ and 11-MeV deuteron beams. Reaction products were magnetically analyzed and recorded on nuclear emulsions. Angular distributions for the first two reactions were analyzed with distorted-wave Born-approximation predictions, and spectroscopic formation was extracted from the data. The $J=2\mathrm{}$ level at 3.06 MeV was assigned positive parity and $T=1\mathrm{}$. The $J=2\mathrm{}$ level at 3.84 MeV was assigned positive parity, and the 4.12-MeV level was assigned $J^{\pi }=3^{+}$. The three levels at 4.65, 4.74, and 4.96 MeV were identified as having $T=1\mathrm{}$. The 4.65-MeV level was assigned $J^{\pi }=4^{+}$, and we have a strong preference for $J^{\pi }=0^{+} \mathrm{and} 2^{+}$ assignments for the 4.74- and 4.96-MeV levels, respectively. Our results are in good agreement with the theoretical predictions of Kuo and Brown.
