Positronium formation with excitation
- 1. UCL Department of Physics and Astronomy, University College London, Gower Street, London, WC1E 6BT (United Kingdom)
Description
Cross-sections for positron-impact ionization leaving either the resultant ion or positronium atom in an excited state are presented. For atomic targets, excited-state positronium contributes significantly to the positronium formation cross-section, while for CO2 and N2 it appears suppressed. Instead, for these targets large cross-sections for ionization-excitation are noted.
