Phys. Rev. A 55, 1533–1536 (1997)Total cross sections of positron scattering from various molecules using the rule of additivity
The total cross sections σt for positron impact on many diatomic and polyatomic molecules have been calculated using the additivity rule in which the total cross section for a molecule is the sum of the total cross sections for the constituent atoms. The energy range is from 10 eV to 5000 eV. The total cross sections for positron impact on an atom are calculated by employing a complex, spherical potential which is comprised of a static, polarization, and an absorption potential. We have good agreement with the available experimental results for positron energy ⩾30 eV. © 1997 The American Physical Society URL:
