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

- 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, two areas were measured in the FIR range: a virgin (=non irradiated) area, and an irradiated one.
