           Absorption coefficient of ion irradiated polystyrene

We measured the changes induced by energetic ion irradiation in the absorption coefficient of the polystyrene in the UV-Vis-NIR wavelength range (250-980 nm). Polystyrene was chosen as a template for organic matter of low volatility that can be present on asteroidal surfaces.

The samples - polystyrene films deposited on quartz substrates - were irradiated in vacuum, at room temperature, with 200 keV protons and 400 keV argon ions.

Data from: Kanuchova, Z., Baratta, G.A., Garozzo, M. and Strazzulla, G.: 2010, Space weathering of asteroidal surfaces. Influence on the UV-Vis spectra, A&A 517, A60
