Abstract
The mean lifetime of the 1.04 MeV (${J}^{\ensuremath{\pi}}={0}^{+},T=1$) state in $^{18}\mathrm{F}$ has been measured to be 2.7\ifmmode\pm\else\textpm\fi{}0.7 fs using the inverse reaction $^{3}\mathrm{He}(^{16}\mathrm{O},p)^{18}\mathrm{F}$ and the Doppler-shift attenuation method. Targets of $^{3}\mathrm{He}$ implanted into Al, Zr, Nb, and Au foils were employed in the measurements. The centroid shifts and Doppler-broadened line shapes observed at 0\ifmmode^\circ\else\textdegree\fi{} were used in obtaining the lifetime value. The lifetime of the 1.04 MeV state is compared with theoretical predictions.NUCLEAR REACTIONS $^{3}\mathrm{He}(^{16}\mathrm{O},p)^{18}\mathrm{F}$, $E=15.9$ MeV; measured Doppler-shift attenuation, $p\ensuremath{\gamma}$ coin. $^{18}\mathrm{F}$ 1.04 MeV level deduced $\ensuremath{\tau}$.
