Abstract
The aim of this project is to experimentally study the interaction between highlycharged ions with the mixture H2O,CO2,CH4(10:1:1) astrophysical ice analogs in physicochemical condition similar to the ones found in interstellar dust regions, comets, transneptunians objects (TNO) and moons (for example Enceladus). As a first step, we will analyze experimental data obtained previously by th…
