A comparison of ion irradiation and UV photolysis of CH4 and CH3OH
摘要：
We present the results of an experimental study of the structural effects induced by Lyman-alpha UV photons in crystalline water ice at low temperature carried out by using in situ infrared spectroscopy. We studied the evolution, under UV irradiation, of the 3 micron band profile. We found that an UV dose of few eV per water ice molecule is enough to fully amorphize the structure at the...
