The absolute total cross section for electron-CH3Br scattering has been measured in a wide energy range (from 0.4 to 250 eV) by the linear transmission method. At the lowest investigated energies the cross section increases rapidly when the energy decreases. A shallow minimum of the total cross section between 2.5 and 4.5 eV followed by a weak broad enhancement around 7 eV is observed. A comparison is made with available data.
