CONDENSATION EXPERIMENT OF ICES FROM THE INTERSTELLAR GAS

Abstract
The importance of ices on the evolution of interstellar space is widely recognized. Some studies, both experimental and theoretical, have been carried out on the condensation of ices from the interstellar gas. However, phase relation of multi-component ices have not be investigated. We have been performing condensation experiment of ices from the gas of interstellar composition analog at temperatures between 10 and 150 K. The structure and chemical composition of the ices are analyzed as a function of condensation temperature by mass spectrometry and X-ray diffraction, respectively. Amorphous-crystal transition of the ices except for H2O ices are also investigated. The result of the experiment will be presented.
