The effect of broadband soft X-rays in SO2-containing ices: implications on the photochemistry of ices toward young stellar objects
S Pilling, A Bergantini - The Astrophysical Journal, 2015 - iopscience.iop.org
We investigate the effects produced mainly by broadband soft X-rays up to 2 keV (plus fast
(∼ keV) photoelectrons and low-energy (∼ eV) induced secondary electrons) in the ice …
