Title: Low-energy Positron Scattering By Co2

Abstract: In this work we present results of integral (ICS) and differential (DCS) cross sections for positron- CO2 scattering at low incident energies. Our ICS shows a significant improvement toward the experimental data, especially below 2 eV, and all the way up to the positronium formation threshold (7.8 eV), in comparison to our previous calculations. Our calculated DCSs show a better resemblance in shape with the quasielastic experimental points of the Detroit group, but the agreement is still not fully satisfactory, indicating a need for further theoretical and experimental investigation. © 2008 The American Physical Society.
