We report quantum mechanical calculations of the differential, momentum transfer, and integral cross sections for electron-CH/sub 4/ elastic scattering in the energy range 20--500 eV. The e/sup -/-CH/sub 4/ interaction term is composed of three local spherical potentials, namely, the static, the exchange, and the polarization. The static potential is generated without additional approximations from near-Hartree--Fock methane wave functions; the exchange interaction is included in the free-electron-gas-exchange (FEGE) model; and for polarization, we employ a parameter-free ab initio potential of Jain and Thompson. All the cross sections are in good accord with recent absolute experiments.
