Abstract
Electron-positron propagators are discussed in the context of the many-body theory of composite electronic-positronic systems. They are shown to be useful for obtaining positron affinities of open-shell systems with one unpaired electron. The approximation schemes obtained are simpler than those in the analogous two-electron case.
