Electron-CH/sub 4/ scattering is investigated in a wide energy range (0.1--500 eV) by using a previously proposed spherical model (A. Jain, J. Chem. Phys. 81, 724 (1984)). The study is divided into three energy regions: the 0.1--1.0-eV region, where a well-known minimum occurs in the total cross section (Ramsauer-Townsend (RT) effect), between 2 and 20 eV, with a d-wave broad structure around 7--8 eV, and from 20 to 500 eV, where inelastic channels (mainly ionization and dissociation) dominate over the elastic process. It is shown that a simple model, in which the total optical complex potential is spherical, is capable of reproducing qualitative features in the total, differential, and momentum-transfer cross sections in the present energy region.
