Abstract

The feasibility of experimentally determining the $S$-wave $\ensuremath{\pi}\ensuremath{\pi}$ phase shifts in the reaction ${e}^{\ensuremath{-}}+{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{\ensuremath{-}}+{e}^{\ensuremath{-}}+{\ensuremath{\pi}}^{+}+{\ensuremath{\pi}}^{\ensuremath{-}}$ is investigated.
