Radiative Lifetimes in the Resonance Series of Ne

Direct measurements have been made of radiative lifetimes of the nine $J=1\mathrm{}$ levels of the $3s$, $4s$, $5s$, and $3d$ configurations in Ne I. Branching ratios have been calculated in the Coulomb approximation, and oscillator strengths are given for all of the above transitions. The $3s$ lifetimes agree well with previous experimental results. The cascade lifetimes determined in a two-exponential model are consistent with known lifetimes of visible transitions.
