- Comments
- We irradiated pellets of different terrestrial phyllosilicates on the SIDONIE isotope separator at IJCLab (Orsay, France) using $Ar^+$ ions at 40 keV. Samples were mounted vertically and ion irradiation was performed at normal incidence. For each sample, we measured, besides the "virgin" spectrum, three separate spectra corresponding to different fluences: $5.10^{15}$, $1.10^{16}$ and $2.10^{16}$ $ions.cm^{-2}$.
