Using single-bunch operation of the Photon Factory and time-correlated single-photon counting, the radiative lifetime of 2s core-hole excited Ne
(1s
2s
2p
) has been determined by detecting fluorescence to the ionic ground state. We compare our results with multi-configuration Dirac-Fock calculations using the GRASP92 code.

In this work we recorded the total ion and fluorescence yield spectra in the region of the Neon 2s2p
) double excitation resonance, near 73.8 eV. Whereas a Fano-like profile was observed in the fluorescence yield spectrum, no structure was visible in the ion yield spectrum. Thus this state appears stable against auto-ionization. Using single-photon counting during single-bunch operation we have separated the fluorescence into three separate components, and it is hoped that these will provide clues to the excitation and decay processes.
