| Description | Journal: Journal of Physics B: Atomic, Molecular and Optical Physics Detailed theoretical studies of annihilation in low-energy positron - atom scattering reveal a very pronounced enhancement of the annihilation rate in the vicinity of the positronium formation threshold, providing qualitative confirmation of the predictions of a recent model in which the enhancement is attributed to virtual positronium formation. The present investigations relate specifically to atomic hydrogen but similar results have also been obtained for helium. From investigations of annihilation at energies above the positronium formation threshold, we conclude that no clear distinction can be made between direct annihilation and annihilation following positronium formation. |
