Infrared resonant desorption of H2O from ice multilayers
Article Abstract:
A study examined the infrared resonant desorption of H2O from ice multilayers in ultrahigh vacuum (UHV). The UHV allowed the analysis of the desorption yield using a quadrupole mass spectrometer, which provided data on the identity and intensity of the desorption yield from each infrared free electron laser pulse. Findings showed that the H2O resonant desorption spectrum was much increased compared to the infrared adsorption spectrum of ice at infrared wavelengths shorter than a lambda of around 3.1 mu m. The H2O desorption yields from thick films conformed to the melting of the ice film and the anticipated optical penetration depths in liquid water.

Surface characterization study of the thermal decomposition of Ag2CO3
Article Abstract:
Ag2CO3, a silver carbonate powder, was examined by X-ray photoelectron spectroscopy to determine the chemical changes caused by thermal decomposition in its surface region. An anneal of 155 degrees C will decompose Ag2CO3 to Ag metal and oxides, a 170 C anneal results in Ag metal, Ag2O and AgO, a 340 C anneal will result in further decomposition to Ag2O and between 340 and 43OC will result only in Ag metal and surface oxygen. The decomposition temperatures were much higher than the amounts estimated by equilibrium thermodynamic calculations.

Band effects on stimulated desorption of F+ from CaF2 and fluorinated TiC(111) surfaces
Article Abstract:
Research into F+ emission from the fluorinated TiC(111) surface by ion beam irradiation is presented. It is concluded that the F+ emission is initiated by formation of the F 2s core-hole state.
