- Comments
- We irradiated pellets of Mercury terrestrial analogues on the SIDONIE isotope separator at IJCLab (Orsay, France) using $He^+$ ions at 20 keV and a fluence up to $5.10^{17}$ $ions.cm^{-2}$ .Two pellets were measured for each type of analogues. For each pellet, half of the samples was measured unirradiated and the other half was measured after irration with He+ with a fluence of $1.10^{17}$ $ions.cm^{-2}$ for the first samples and $5.10^{17}$ $ions.cm^{-2}$ for the second sample (bis).
