Abstract.

Electron impact total (50 to 2000 eV) and ionization (threshold to 2000 eV) cross-sections are calculated using the SCOP and CSP-ic methods [Phys. Rev. A 69, 022705 (2004)] for the hydrocarbon molecules (CH4, C2H2, C2H4, C2H6, C3H4, C3H6 and C3H8) and radicals (CHx (x=1-3)). Present method has already been tested successfully to many other aeronomic [Int. J. Mass Spectrom. 233, 207 (2004)] and plasma molecules and radicals. Our results exhibited in this paper show good agreement with experimental results where available. For the radical species, we have presently done a first estimate of the total cross-sections.
