Abstract
New measurements of the total cross sections for positron scattering by helium and by neon are tested for consistency with a sum rule based on forward dispersion relations. The real parts of the forward scattering amplitudes are calculated and compared with recent theoretical predictions. Revised values of the real part of the forward scattering amplitude for electron scattering by helium are presented.Keywords
