To test proposals for the origin of oxygen absorption bands in the visible reflectance spectrum of Ganymede, the reflectance of condensed films of pure oxygen (O2) and O2-water mixtures and the evolution of O2 from the films as a function of temperature were determined. Absorption band shapes and positions for oxygen at 26 kelvin were similar to those reported for Ganymede, whereas those for the mixtures were slightly shifted. The band intensity dropped by more than two orders of magnitude when… Expand
Laboratory studies of the optical properties and stability of oxygen on Ganymede
We present measurements of the optical properties of solid O2 and O2:H2O films and on the stability of oxygen in water ice at different temperatures. The experiments are meant to test hypotheses forExpand
The Geographic Distribution of Dense-phase O2 on Ganymede
Ground-based spectroscopy of Ganymede’s surface has revealed the surprising presence of dense-phase molecular oxygen (O2) via weak absorptions at visible wavelengths. To date, the state and stabilityExpand
Uv-Vis, Infrared, and Mass Spectroscopy of Electron Irradiated Frozen Oxygen and Carbon Dioxide Mixtures with Water
Ozone has been detected on the surface of Ganymede via observation of the Hartley band through the use of ultraviolet spectroscopy and is largely agreed upon to be formed by radiolytic processing viaExpand
Production of O2 on icy satellites by electronic excitation of low-temperature water ice
TLDR
The large cross-section for O2 production suggests that electronic excitation plays an important part in the formation of O2 on Ganymede and Europa, rather than by diffusion and chemical recombination of precursor fragments as has been previously thought. Expand
Photolysis of pure solid O3 and O2 films at 193 nm.
TLDR
The general good agreement of the model with the data suggests the validity of the central assumption of efficient energy and spin relaxation of photofragments in the solid prior to their reactions with other species. Expand
Laboratory studies on the formation of ozone (O3) on icy satellites and on interstellar and cometary ices
The formation of ozone (O3) in neat oxygen ices was investigated experimentally in a surface-scattering machine. At 11 K, solid oxygen was irradiated with energetic electrons; the chemicalExpand
Comment on “Laboratory studies of the optical properties and stability of oxygen on Ganymede” by Raul A. Baragiola and David A. Bahr
It has been over 15 years since Brown et al. [1982] showed that the bombardment of the icy satellites by magnetospheric plasma particles would produce significant quantities of O2, including an O2Expand
Decomposition of solid amorphous hydrogen peroxide by ion irradiation.
TLDR
From the measurements, radiation yields are derived, which are found to be particularly high for the decomposition of hydrogen peroxide; this can be explained by the occurrence of a chemical chain reaction. Expand
A review of possible optical absorption features of oxygen molecules in the icy surfaces of outer solar system bodies
Abstract In this review we provide the data needed to interpret remote spectroscopic studies of O2 molecules embedded in the icy surfaces of outer solar system bodies. O2 produced by radiolysis hasExpand
Physical and Chemical Alterations of Ices by Fast Proton Irradiation, Particularly Ozone Synthesis
Abstract : In this thesis, we investigated the interaction of 100 keV protons with thin ice films grown under ultra-high vacuum conditions. We determined irradiation of pure water ice produced anExpand

Weak absorption features in the visible reflectance spectrum of Jupiter's satellite Ganymede have been correlated to those observed in the spectrum of molecular oxygen. We examine the spectralExpand
Detection of Ozone on Ganymede
TLDR
An absorption band at 260 nanometers on the trailing hemisphere of Ganymede, identified as the Hartley band of ozone (O3), was measured with the Hubble Space Telescope, and apparently this O2-O3 “atmosphere” is trapped in GanyMede's surface ice, an inference consistent with the shift and broadening of the band.

TLDR
It is found that fresh films have an enhanced sublimation rate, which decays in time and which depends on film thickness and growth temperatures, and this is attributed to sublimating from regions containing amorphous ice, which transforms with time into the less volatile crystalline ice. Expand

TLDR
The structural transition from Iah to Ial is responsible for the diffusion and recombination of radicals in ultraviolet-photolyzed interstellar ices at low temperatures and can be used to explain hitherto anomalous properties of astrophysical ices. Expand
