Abstract

The two-photon resonances of atomic hydrogen (lambda = 2 X 205.1 nm), atomic nitrogen (lambda = 2 X 206.6 nm) and atomic oxygen (lambda = 2 X 225.6 nm) are investigated together with two selected transitions in krypton (lambda = 2 X 204.2 nm) and xenon (lambda = 2 X 225.5 mn). The natural lifetimes of the excited states, quenching coefficients for the most important collisions partners, and the relevant ratios of the two-photon excitation cross sections are measured. These data can be applied to provide a calibration for two-photon laser-induced fluorescence measurements based on comparisons with spectrally neighbouring noble gas resonances.
