We measured the absolute desorption yield of water and carbon dioxide films condensed at low temperatires under irradiation with Lyman-@alpha@ (121.6 nm) photons as a function of sample temperature and irradiation fluence using a double quartz-crystal resonator. We also determined the species desorbed using mass spectrometry. We will discuss the results in terms of basic processes and discuss astrophysical implications.
