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 (
)). 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.
