Description
MIR spectra of phyllosilicate pellets irradiated by $Ar^+$ or $He^+$.
Number of spectra
9
Variable type(s)
  • sample composition
  • irradiation type
Comments
We irradiated pellets of different terrestrial phyllosilicates on the SIDONIE isotope separator at IJCLab (Orsay, France) using $Ar^+$ ions or $He^+$ . Samples were mounted vertically and ion irradiation was performed at normal incidence. For each sample, we measured, besides the "virgin" spectrum, two separate spectra corresponding to irradiation by $Ar^+$ and $He^+$.
