The formation and dissociation of [Formula: see text] in an atomic beam by ruby laser radiation have been observed. Values of the dissociation energy of [Formula: see text] have been determined by the time of flight of the resulting Na+ ions and the potential needed to stop them. These results, with a mean of 1.02 ± 0.09 eV, have been compared with the calculated and observed values of others. The effects of laser polarization vs. dimer axis orientation have been clearly demonstrated.

State Dissociation

Multiphoton ionization of K2, Rb2, and Cs2 in beam conditions by pulsed ruby laser radiation (λ = 6946.0 Å, pulse duration ~10 ns) and subsequent dissociation of the dimer ions by one or more additional photons have been observed. Ground-state dissociation energies of these ionic species have been determined directly from the time of flight of the dissociation fragment pairs, and from the use of retarding potentials, to be [Formula: see text], [Formula: see text], and [Formula: see text]. These observed values have been compared with the theoretical and experimental work of other authors. Our results for the [Formula: see text] and [Formula: see text] ions are the first direct measurements of their ground-state dissociation energies. The effect of laser polarization on the dissociation mechanism has also been experimentally investigated.

Photon Process

Ionization of Li resulting from the interaction of pulsed single-mode (λ = 694.60 ± 0.05 nm, TEM00) ruby laser radiation with an atomic beam was observed. The results can be interpreted in terms of a four-photon process with three-photon resonances with levels in the vicinity of the 19P and 20P Rydberg levels of the unperturbed atom. Both linearly and circularly polarized light were used. The results are compared with the calculated results of others.

Photon Ionization

Single mode ruby laser radiation (694 nm) and an atomic beam apparatus have been used in the study of the three photon ionization of Na, K, Rb, and Cs atoms. The process in all cases is nonresonant, the observations being consistent with a rate given by W3F3 where F is the photon flux. The values obtained for W3l (linear polarization) and W3C (circular polarization) and the ratio W3c/W3l are discussed in relation to recently calculated results and the few other experimental results available. Discrepancies well beyond the assigned errors exist between experimental and calculated results.
