Differential cross sections for elastic scattering of positrons by magnesium atom in the intermediate energy region from 300 to 500 eV have been calculated by employing distorted wave approach. A suitable form of polarization has been used. To observe the impact of polarization effect, differential cross sections have been calculated with and without polarization potential. The first -Born results have been reported. The aqreement between present set of results with corresponding theoretical predictions in literature is fair.
