![Simulation results of abundance ratios [H2O2]/[H2O] (black lines), [H2]/[H2O] (orange lines), and [O2]/[H2O] (blue lines) with our model (model A) at 16 K (solid lines) and 77 K (dashed lines). The gray shaded and line filled regions show the experimental results of [H2O2]/[H2O] by Gomis et al. (2004a) at 16 and 77 K, respectively, with an assumed uncertainty of a factor of 3. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Simulation-of-proton-radiolysis.png?resize=1200%2C719&ssl=1)
The radiolysis effect of cosmic rays (CRs) plays an important role in the chemistry in molecular clouds. CRs can dissociate the molecules on dust grains, producing reactive suprathermal species and […]
