Abstract
In a triple, orthogonal crossed beam experiment, we have studied photoionization of excited Na atoms. A cw ring dye laser (few W/cm2) locked to the D1 or D2 absorption lines excited up to 20% of the 201 3 cm− 3 ground state atoms to Na(3p 2 p 3/2). Monochromatized synchrotron radiation from the ACO storge ring provided the photoionizing radiation. A cylindrical mirror electron spectrometer was used to measure photoelectron spectra. First measurements of the 2p 63p→2p 53p E l photoionization were obtained. Decay of autoionizing resonances to the 2p 53p ionic channel were also observed.Keywords
