Description: Mid-IR spectra of methanol ice, at 45 K, increasing irradiation doses: unirradiated and irradiated by $H^+$ ions at 30 keV and a total fluence of $1.10^{16} ions.cm{-2}$ .
Number of spectra: 6

Variable type(s)

Comments

We irradiated methanol ice on the SIDONIE isotope separator at IJCLab (Orsay, France) using

$H^+$ ions at 30 keV and a total fluence of

$1.10^{16}$

$ions.cm^{-2}$ . Reference spectra were collected on the MgF2 substrat. Spectra are corrected for athmospheric contribution (CO2 and H2O).

Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°-i).
