Proton Groups from the Deuteron Bombardment ofF19andP31

The ${\mathrm{F}}^{19}\mathrm{}(d,p)\mathrm{}{\mathrm{F}}^{20}$ and ${\mathrm{P}}^{31}\mathrm{}(d,p)\mathrm{}{\mathrm{P}}^{32}$ reactions were studied with 3.76-Mev cyclotron deuterons. The ${\mathrm{F}}^{19}\mathrm{}(d,p)\mathrm{}{\mathrm{F}}^{20}$ ground-state $Q$-value was found to be 4.16±0.08 Mev, giving 1.00211±0.00010 MU for the ${\mathrm{F}}^{20}$-${\mathrm{F}}^{19}$ mass difference and 20.00660±0.00012 MU for the mass of ${\mathrm{F}}^{20}$. Excited states of ${\mathrm{F}}^{20}$ were found at 0.64, 0.97, 1.31, 1.91, 2.52, 2.83, 3.45, and 4.01 Mev. The ${\mathrm{P}}^{31}\mathrm{}(d,p)\mathrm{}{\mathrm{P}}^{32}$ ground-state $Q$-value was found to be 5.52±0.10 Mev, giving 1.00065±0.00011 MU for the ${\mathrm{P}}^{32}$-${\mathrm{P}}^{31}$ mass difference, and 30.98286±0.00021 MU for the mass of ${\mathrm{P}}^{31}$. Excited states of ${\mathrm{P}}^{32}$ were found at 0.50, 1.10, 1.36, 1.71, 2.22, 2.72, and 3.27 Mev.
