โœฆ Synopsis

The total electron scattering cross sections (TCS) of C 2 H 2 and C 3 H 4 have been obtained for 200-4500 eV electrons by measuring the attenuation of the electron beam through a gas cell. An empirical expression is deduced to express the TCS of normal hydrocarbons as a function of the number of atomic constituencies in the hydrocarbon and the electron energy.

We report converged quantum total integral reactive cross sections for the reaction F+H,+HFt H, for initial rotational states jl=O and I, using a time-dependent method. Our results are compared to classical results and to the experimental results of Nemnark et al. Strong quantum effects are found in
