Espalhamento Elástico de Pósitrons por Moléculas Diatômicas Apolares

Abstract

In this work we study the elastic scattering of positron from non-polar diatomic molecules H2 and N2. We used the FNMC methodology implemented in the eletronic computational package called GAMESS to obtain the potential energy surfaces of the e +H2 and e +N2 systems. To obtain the scattering matrix and the integral cross section we used the Method of the Continued Fractions for both sistems.
