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 sect

✦ Synopsis
Absolute electron-scattering total cross sections for methyl iodide have been measured at impact energies between 0.5 and 220 eV using a linear transmission method. The cross section increases rapidly as the energy becomes smaller than 1.5 eV, has a minimum (50X lO-zo m') around 2.5 eV followed by a broad maximum (58 X I Wzo m') centered close to 6.5 eV, and monotonically decreases at higher energies.

The absolute total cross section for electron scattering on C,H, molecules has been measured in two distinct electron-transmission experiments for impact energies between 0.6 eV and 3.5 keV. The present results are compared with other total cross section experimental data.
Measurements made on H2S in the energy range 1.3-70 eV give total electron-scattering cross sections which exhiiit two distinct features: a shoulder at about 2.3 eV and a very broad hump centered at 9 eV with a maximum value of 40 X 10m20 m2. These results are in agreement with those calculated by J
