Abstract
A study of elastic scattering of electrons and positrons by helium in its ground as well as its metastable states has been done using a model-potential approach. Reliable static, polarization, and exchange potentials are used to describe the scattering process. Elastic differential and total cross sections are obtained in a wide range of incident projectile energy, viz., from nearly very low energy to 1000 eV. Our results are compared with available experimental data and other theoretical results.Keywords
