摘要
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.
