- Description
- Vis and Near-IR spectra of a pellet of "Saponite Griffithite", with different irradiation fluences.
- Number of spectra
- 4
- Variable type(s)

- irradiation dose
- Comments
- We irradiated a pellet of Saponite on the SIDONIE isotope separator at IJCLab (Orsay, France) using ions at 40 keV. The sample was mounted vertically and ion irradiation was performed at normal incidence. We measured four separate spectra corresponding to different fluences: , and .
