/ Dupuy, R (LERMA, Ivry) ; Bertin, M (LERMA, Ivry) ; Féraud, G (LERMA, Ivry) ; Romanzin, C (LCP, Orsay) ; Putaud, T (LERMA, Ivry) ; Philippe, L (LERMA, Ivry) ; Michaut, X (LERMA, Ivry) ; Jeseck, P (LERMA, Ivry) ; Cimino, R (Frascati) ; Baglin, V (CERN) et al.
We report an investigation of X-ray induced desorption of neutrals, cations and anions from CO ice. The desorption of neutral CO, by far the most abundant, is quantified and discussed within the context of its application to astrochemistry. [...]

Photodesorption of Water Ices: Highlights from Recent Synchrotron Radiation Studies
/ Fillion, Jean-Hugues (Paris Observ.) ; Dupuy, Rémi (Paris Observ.) ; Féraud, Géraldine (Paris Observ.) ; Romanzin, Claire (ICM, Paris) ; Marie-Jeanne, Patrick (Paris Observ.) ; Jeseck, Pascal (Paris Observ.) ; Baglin, Vincent (CERN) ; Cimino, Roberto (LNF, Dafne Light) ; Michaut, Xavier (Paris Observ.) ; Bertin, Mathieu (Paris Observ.)
UV-X photodesorption of water ices, which is playing a role on the gas-to-ice ratio in a wide range of astrophysical environments, has also been extensively studied in the laboratory. In recent years, the SPICES setup coupled to several beamlines at the SOLEIL facility (France) has allowed the analysis of water photodesorption spectra (PSD) in the vacuum-UV (VUV) and soft X-ray range.

Paris-Sud 11, Dept. Phys., Orsay ; U. Paris-Saclay) et al.
Electronic excitations near the surface of water ice lead to the desorption of adsorbed molecules, through a so far debated mechanism. A systematic study of photon-induced indirect desorption, revealed by the spectral dependence of the desorption (7 to 13 eV), is conducted for Ar, Kr, N$_{2}$, and CO adsorbed on H$_{2}$O or D$_{2}$O amorphous ices.

Vacuum-UV photodesorption from compact Amorphous Solid Water : photon energy, isotopic and temperature effects

Vacuum-UV (VUV) photodesorption from water-rich ice mantles coating interstellar grains is known to play an important role in the gas-to-ice ratio in star- and planet-forming regions. Quantitative photodesorption yields from water ice are crucial for astrochemical models. [...]

Desorption of neutrals, cations, and anions from core-excited amorphous solid water

Core-excitation of water ice releases many different molecules and ions in the gas phase. Studying these desorbed species and the underlying mechanisms can provide useful information on the effects of X-ray irradiation in ice. [...]

Photon-stimulated desorption (PSD) is a process of interest for the two seemingly unrelated topics of accelerator vacuum dynamics and astrochemistry. Here we present an approach to studying PSD of interstellar ice analogs, i.e. [...]

The efficient photodesorption of nitric oxide (NO) ices

The study and quantification of UV photon-induced desorption of frozen
molecules furthers our understanding of the chemical evolution of cold
interstellar regions. Nitric oxide (NO) is an important intermediate species in
both gas-phase and solid-phase chemical networks. [...]
