	abstract = {We report the observation of above-threshold dissociation of a multielectron molecular system, Na-2(+). The process is due to continuum-continuum transitions in a field-dressed molecular continuum. Three well-resolved fragmentation channels with different kinetic energy release patterns have been detected, of which two are associated with ordinary photodissociation via "light-induced potentials" into Na(3s)+Na+ and Na(3p)+Na+, and one with continuum-continuum transitions and above-threshold dissociation into Na(3p)+Na+. We show that when we dress this molecule with a field whose intensity is similar to 3 X 10(12) W/cm(2), above-threshold dissociation prevails over other processes, such as field ionization followed by Coulomb explosion.},

	abstract = {The development and characterization of a new instrument for solid sampling which couples IR laser desorption followed by UV laser photo-ionization and analysis using an ion trap mass spectrometer has been investigated. For calibration, a new type of solid sample preparation involving activated charcoal as the solid substrate was used. This solid sample provided a steady signal for several thousand laser shots, which allowed optimization of the experimental procedure. It was found that both the IR and UV intensity and the delay between them play an important role in both the magnitude and type of signals observed. A method of gas phase accumulation with multiple laser shots was examined. Finally, this technique was demonstrated to be effective in providing direct qualitative information. for N.I.S.T.
