The detection of ozone (O3) in the surface ices of Ganymede, Jupiters largestmoon, and of the Saturnian moons Rhea and Dione, has motivated several studieson the route of formation of this species. Previous studies have successfullyquantified trends in the production of O3 as a result of the irradiation ofpure molecular ices using ultraviolet photons and charged particles (i.e., ionsand electrons), such as the abundances of O3 formed after irradiation atdifferent temperatures or using different charged particles. In this study, weextend such results by quantifying the abundance of O3 as a result of the 1 keVelectron irradiation of a series of 14 stoichiometrically distinct CO2:O2astrophysical ice analogues at 20 K. By using mid-infrared spectroscopy as ourprimary analytical tool, we have also been able to perform a spectral analysisof the asymmetric stretching mode of solid O3 and the variation in its observedshape and profile among the investigated ice mixtures. Our results areimportant in the context of better understanding the surface composition andchemistry of icy outer Solar System objects, and may thus be of use to futureinterplanetary space missions such as the ESA Jupiter Icy Moons Explorer andthe NASA Europa Clipper missions, as well as the recently launched NASA JamesWebb Space Telescope.
