    Title: TOTAL ION DESORPTION YIELDS OF H2O, D2O, CH3OH, CD3OD AND WATER-METHANOL MIXED ICES IRRADIATED AT 584 ANGSTROM

    Abstract: Preliminary measurements of the total ion desorption yields of several pure and mixed molecular ices have been carried out using the He I 584 angstrom resonance radiation as the incident photon beam. The various ice samples were prepared at 77 K in an ultrahigh vacuum system. The total ion desorption yields of H2O ices, D2O ices, CH3OH ices, CD3OD ices, H2O-CH3OH mixed ices and D2O-CD3OD mixed ices were determined. Minor isotopic effects on the ion desorption processes of the above-mentioned ices have been observed. There is a clear enhancement in the ion desorption yields of water-methanol mixed ices in comparison with pure ices. Such data are required in the interpretation of the gaseous atmospheres of comets, asteroids, icy planets, satellites and rings, and interstellar icy grains.
