Experimental absolute differential cross sections are presented for elastic scattering of 20-200 eV electrons from the noble gases, with an angular resolution better than 0.25 degrees . A novel type of parallel-plate electrostatic energy analyser is

A dispersion relation for forward scattering, as formulated by Gerjuoy and Krall (1960) is studied numerically for electron and positron scattering by helium. The real part of the scattering amplitude for elastic scattering at impact energy E and sca

Numerical studies of the dispersion relation for forward scattering are reported for electrons scattered by atomic hydrogen. As has previously been shown for electron-helium scattering, the relation of Gerjuoy et al. (1960, 1972) has to be modified.

Total cross sections for electron scattering by H2 are obtained for impact energies ranging from 25 to 750 eV. The method used is a linearisation of the Ramsauer-type experiment, which enables good angular and energy resolution; the accuracy obtained

Total cross sections have been remeasured for 20-100 eV electron scattering from Ar, Kr and Xe, achieving an accuracy of better than 5%. In the present measurements a short collision cell of adjustable length has been used, which permitted the applic

Total cross sections have been measured for electron scattering on Ne, Ar, Kr and Xe in the impact energy range between 25 and 750 eV. The method used has been introduced by Blaauw et al. (1980) for the same measurement with He and N2 as targets. It

An apparatus has been constructed to measure the total cross section for electron scattering by atoms and molecules. It can be viewed as a linearisation of the Ramsauer technique with a well defined solid angle for the analyser/collector. Measurement
