| Abstract: | The elastic scattering of a positron by a hydrogen atom is studied by using the variable-phase approach to potential scattering. Values of the scattering length and the elastic scattering phase shifts obtained in the (i) static, (ii) polarization and (iii) extended polarization approximations for the e+?H interaction are found to be in close agreement with the results of earlier workers. |
