Beta-Delayed Protons fromNe17

${\mathrm{Ne}}^{17}$ was produced by the (${\mathrm{He}}^3,2n$) reaction on thin ${\mathrm{Al}}_2$ ${\mathrm{O}}_3$ and gaseous ${\mathrm{O}}_2$ targets, using the 32-MeV ${\mathrm{He}}^3$ beam of the Brookhaven 60-in. cyclotron. In addition to previously reported delayed proton groups, new groups were observed at center-of-mass energies of 3.72, 6.12, and 10.48 MeV, and the half-life was determined to be 105±5 msec. The highest-energy proton group, which constitutes 0.04% of the total protons observed, corresponds to decay of the analog state of ${\mathrm{Ne}}^{17}$ at an excitation energy of 11.08±0.08 MeV in ${\mathrm{F}}^{17}$.
