Description
Measurements of that part of the total positron-helium cross section not associated with positronium formation have been made for positron energies between 14 and 28 eV. The experimental results do not support the existence of a cusp in the elastic scattering cross section at the positronium formation threshold energy (17.8 eV) as significant as that previously deduced by other authors.
