Description
VIS-NIR spectra of Mercury terrestrial analogues pellets: unirradiated area and area irradiated by He+ ions at 20 keV and a fluence up to 5.1017ions.cm2.
Number of spectra
25
Variable type(s)
  • sample composition
  • irradiation dose
Comments
We irradiated pellets of Mercury terrestrial analogues on the SIDONIE isotope separator at IJCLab (Orsay, France) using He+ ions at 20 keV and a fluence up to 5.1017 ions.cm2 .Two pellets were measured for each type of analogues. For each pellet, half of the samples was measured unirradiated and the other half was measured after irration with He+ with a fluence of 1.1017 ions.cm2 for the first samples and 5.1017 ions.cm2 for the second sample (bis).
