✦ Synopsis
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.

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
Absolute total cross sections for electron scattering from nitrogen dioxide have been measured in a linear transmission experiment from 0.6 to 220 eV. A minimum cross section occurs around 3 eV followed by a very broad maximum near 10 eV, with monotonic decrease at higher energies.
Measurements are made on water vapour in the energy range 0.5-80 eV to give absolute total electron-scattering cross sections. The total cross section function obtained increases sharply at energies below 3 eV and shows a structureless, very broad flat maximum around 9 eV. The results presented here
