Abstract
We report a new measurement of the photoionization cross section for the state of neon at the wavelengths of 351 and . These data were obtained by monitoring the decay of the fluorescence of atoms trapped in a magneto-optical atom trap under the presence of a photoionizing laser, a technique developed by Dinneen et al. [Opt. Lett. 17, 1706 (1992)]. We obtain absolute photoionization cross sections of at and at , an improvement in accuracy of a factor of 4 over previously published values. These new values are not consistent with published theoretical data.
