Secondary neutrals sputtered by 3-keV Ar+ from FeS2 and Fe were studied by use of laser postionization mass spectrometry and laser-induced fluorescence spectroscopy. The velocity distribution and yield of Fe from the FeS2 sample were measured. The ve

Among the many uses of resonantly enhanced multiphoton ionization (REMPI) spectroscopy, secondary neutral mass spectrometry (SNMS) is both one of the most demanding and one of the most important. Recently, we have demonstrated that the selectivity of

Two-photon Doppler-free laser-induced fluorescence spectroscopy has been used for the first time to measure isotope shifts between the three most abundant stable isotopes of zinc (64, 66 and 68). A high-resolution laser system, consisting of an argon

Neutral species ejected from single crystals of ZnS, CdS, and FeS{sub 2} during ion bombardment by 3 keV Ar{sup +} were detected by laser post-ionization followed by time-of-flight mass spectrometry. While metal atoms (Fe, Zn, Cd) and S{sub 2} were t

The photoionization of sputtered Cu, Al, and Ru atoms and dimers was investigated by measuring velocity distributions using both resonant and nonresonant photoionization. Nonresonant ionization produced an atomic distribution that peaked at the same

A laser system for impurity diagnostics in the edge region of plasma devices is described. It consists of a scanning, single mode, cw dye laser followed by a 3-stage, fast flow dye cell amplifier, pumped by a high repetition rate excimer laser (60 mJ

Because of the practical importance of sputtering, numerous theories and computer simulations are used for predicting many aspects of the sputtering process. Unfortunately, many of the calculated sputtering results are untested by experiment. Until r

Physicochemical and thermodynamic studies of liquid-lithium-containing systems have continued. Pressure-composition isotherms for the lithium-hydrogen system measured by a gravimetric technique are found to be in reasonably good agreement with earlie
