G. Garcia et F. Blanco, Energy dependence of the total cross section for electron scattering by chloromethanes in the energy range 0.5-10 keV - art. no. 044702, PHYS REV A, 6204(4), 2000, pp. 4702
The energy dependence of the total cross section for electron scattering by
methane and its chloride compounds has been studied by considering the lat
est experimental results and those predicted by the Born-Bethe theory. A si
mple analytical expression depending on the number of electrons and the pol
arizability of the target is proposed for these molecules. The energy depen
dence given by this formula shows an asymptotic behavior for increasing ene
rgy in better agreement with the Born-Bethe theory. The inconsistency with
the Born-Bethe theory of the two-parameter formula given recently by Karwas
z et nl. has also been shown.
