Photo-atomic effect: Temperature dependence of the photodesorption of Na and from polymer surfaces
Alkali metals adsorbed to surface films of the polymer poydimethylsiloxane (PDMS) have been shown to exhibit a unique photodesorption behavior, characterized by a frequency threshold and high efficiency. In th...

Light-induced ejection of alkali atoms in polysiloxane coated cells
An intense laser-induced fluorescence of sodium and of other alkali atoms (K, Rb) at room and lower temperatures has been observed in polysiloxanecoated cells, producing a vapor density of the metal which is m...

Nonabsorption hyperfine resonances in a sodium vapour irradiated by a multimode dye-laser
The fluorescence intensity of a sodium vapour excited by a multimode dye-laser is observed as a function of the applied magnetic field: a resonant decrease of the fluorescence occurs when the frequency differe...

An experimental method for the observation of r.f. transitions and laser beat resonances in oriented Na vapour
A method which allows a direct picture of phenomena involving line broadening, light shifts and many-photon transitions in the ground state of sodium atoms pumped by dye-laser is reported. A new phenomenon due...
