摘要: A triple-coincidence, five-parameter technique was employed to search for two-photon emission in the decay of $^{16}\mathrm{O}$(6.05-MeV) state. Data were event-recorded and analyzed parallel with events associated $^{16}\mathrm{O}$(6.13-MeV) $^{16}\mathrm{O}$(7.12-MeV) states. Our measured branching ratio is $\frac{{N}_{\ensuremath{\gamma}\ensuremath{\gamma}}}{{N}_{\ensuremath{\pi}}}=(2.5\ifmmode\pm\else\textpm\fi{}1.1)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$.
