Low-energy elastic scattering of positrons by N2O

Ver documento

Detalhes bibliográficos
Resumo:Abstract: We present a theoretical investigation on positron scattering by N2O. Elastic differential and integral cross sections at both the static and static plus correlation-polarization levels of approximation are calculated and reported in the 0.1-100 eV. Calculations were performed using two theoretical methods, namely, the Schwinger multichannel method and the method of continued fractions. Also, two different schemes were used to treat correlation-polarization effects. The comparison between our calculated results and the existing experimental data is encouraging
