In a triple, orthogonal crossed beam experiment, the authors studied photoionization of excited Na atoms. A cw ring dye laser (few W/cm/sup 2/) locked to the D/sub 1/ or D/sub 2/ absorption lines excited up to 20% of the 10/sup 13/ cm/sup -3/ ground state atoms to Na(3p /sup 2/P/sub 3/2/). Monochromatized synchrotron radiation from the ACO storage ring provided the photoionizing radiation. A cylindrical mirror electron spectrometer was used to measure photoelectron spectra. First measurements of the 2p/sup 6/3p ..-->.. 2p/sup 5/3pelement ofel photoionization were obtained. Decay of autoionizing resonances to the 2p/sup 5/3p ionic channel were also observed.
