机译：A New Method for Low Energy (0ndash;10 eV) Ionhyphen;Gas Total Cross Sections Using an Electrostatic Repulsion Technique
A method is described for measurement of low energy total cross sections using an analysis of the uncollided portion of the beam by electrostatic repulsion. Instead of energy separation of the initial beam, a (retarded) spectrum of energies (0ndash;10 eV) is accepted and analyzed with and without interactions. The method applies, in principle, to energies arbitrarily close to zero, limitations occurring in beam intensity and in the smallness of energy group treated in the associated computer analysis. A further limitation is that only large angle scattering is measured. Test measurements for argon ions in argon gas show total cross sections above 1 eV to be indistinguishable from quoted values of charge transfer. In the vicinity of 1 eV a steep rise in cross section is observed.
