- Description
- Mid-IR spectra of carbonaceous chondrite pellets and chips: unirradiated area and area irradiated by $He^+$ ions at 4, 15, 20 and 40 keV and a total fluence of $6.10^{16} ions.cm{-2}$.
- Number of spectra

- sample composition
- irradiation dose
- Comments
- We irradiated pellets of different carbonaceous chondrites on the SIDONIE isotope separator at IJCLab (Orsay, France) using $He^+$ ions at 40 keV and a total fluence of $6.10^{16}$ $ions.cm^{-2}$ . For each samples, several areas were measured in the MIR range corresponding to an unirradiated area and to different doses of irradiation.
