Abstract
Iterative Schwinger variational methods and the method of continued fractions, widely used for electron–molecule scattering, are applied for the first time to investigate positron–molecule interactions. Specifically, integral and differential cross sections for elastic positron scattering by CO in the (0.5–20)eV energy range are calculated and reported. In our calculation, a static plus correlation–polarization potential is used to represent the collisional dynamics. Our calculated results are in general agreement with the theoretical and experimental data available in the literature.
