The mass uptake of ambient oxygen in nanoporous ice is enhanced by irradiation with 193 nm photons, due to conversion of O2 into H2O2 and O3, with an efficiency that increases with decreasing temperature. These findings show a new way to form H2O2 and O3 on icy surfaces in the outer solar system at depths much larger than are accessible by typical ionizing radiation, with possible astrobiological implications.
