“…This is probably amplified in the case of the CH 3 CH 2 OCH 2 CH 3 ice, where each molecule has four carbon atoms, against one oxygen, that are capable of channelling the secondary electron energies towards reactive routes. 81,82,[88][89][90][91] EPD of C 6 H 6 from CH 3 OH and CH 3 CH 2 OCH 2 CH 3 ices is still observed. Although this is a rather minor process, more so in CH 3 CH 2 OCH 2 CH 3 than in CH 3 OH, both a prompt and a dose-dependent component are noted.…”

Desorption of benzene (CH) from thick methanol (CHOH) and diethyl ether (CHCHOCHCH) ices during irradiation with 250 eV electrons is reported and compared with our previous work on CH desorption from water (HO) ice systems. CH electron-promoted desorption (EPD) is seen to be sensitive to the chemical nature of the substrate reflecting both the importance of the excitations localised around the O-atom versus those involving the C-atom; and the role of hydrogen bonding interactions in transporting non-dissociative electronic excitation to the substrate/CH interfaces during the electron irradiation.

Several ionization and dissociation channels of electron interaction with the methane molecule are studied using the recently discovered robust scaling law [D. A. Erwin and J. A. Kunc, Phys. Rev. A 72, 052719 (2005)], other experimentally observed relationships between the ionization and dissociation channels, and the most recent information about the processes. The resulting cross sections for the channels are given in the form of analytical expressions valid at all nonrelativistic energies.
