Abstract
It is suggested that nuclear reactions induced by medium mass projectiles, with A/q close to that of the primary beam, could explain the anomalous positron-electron peaks observed in sub-barrier collisions of very heavy nuclei. The reactions result in prominent γ-rays which convert to e+e− pairs in material near the target. Possible experiments to examine this hypothesis are suggested.
