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+.
