Energy Levels ofF20up to 6.043-MeV Excitation

The reactions ${\mathrm{O}}^{18}({\mathrm{He}}^3, p){\mathrm{F}}^{20}$ and ${\mathrm{F}}^{19}(d, p){\mathrm{F}}^{20}$ have been used to study levels in ${\mathrm{F}}^{20}$ up to an excitation energy of 6.043 MeV. The energies of the reaction protons were measured with a broad-range magnetic spectrograph. Excitation energies were obtained for 45 levels in ${\mathrm{F}}^{20}$. The ground-state $Q$ values for the above reactions were also measured and found to be 6.8752±0.0015 MeV for the ${\mathrm{O}}^{18}({\mathrm{He}}^3, p){\mathrm{F}}^{20}$ reaction and 4.3777±0.0009 MeV for the ${\mathrm{F}}^{19}(d, p){\mathrm{F}}^{20}$ reaction.
