Elastice±−Hescattering with the use of the model-potential method

A model-potential method has been used to evaluate the elastic $e^{\pm }-\mathrm{H}\mathrm{e}$ scattering at the low-incident energies. The potential contains one parameter to include the effect of short-range correlation. The results for the elastic $e^{\pm }-\mathrm{H}\mathrm{e}$ scattering have been obtained using the same parameter. Two model exchange potentials, one for $s$ wave and the other for higher partial waves, have been employed. The present results are in good agreement with the measured values and refined theoretical predictions.
