Positronium formation in positron-Li and positron-Na collisions at low energies
We present the positronium formation cross sections for a positron colliding with lithium and sodium for the collision energies from 0.01 eV up to 20 eV by the hyperspherical close-coupling method. For Li, our results agree with the experimental data and with other calculations. Our results for Na remain in agreement with previous close-coupling calculations, but do not support the latest exper...
متن کاملNew achievements in positron and positronium chemistry
This conference PPC-8 highlighted some of the most important developments in positron and positronium chemistry. New chemistry was considered in the presentation of J.Y. Jean on the use of intense slow positron beam, while A.P. Mills, Jr. discussed the possibility of chemistry and physics with many positrons. These studies are likely to lead to new atoms and molecules—as was discussed in part b...
متن کاملUnified treatment of positron annihilation and positronium formation.
The effects of the positron (e(+)) annihilation in e(+) scattering by the H atom are included directly in the Hamiltonian as an absorption potential, and hence the finite lifetimes Gamma(ns) of positronium (Ps) in states ns are automatically taken account of. The Schrödinger equation is solved using the hyperspherical close-coupling method. The annihilation and Ps formation are shown to be inse...
متن کاملNew experiments with bright positron and positronium beams
After half a century of work studying the interaction of positrons with ordinary matter, there remain several interesting fundamental questions that are uniquely suitable for investigation using antimatter, and several instances where interesting views of the world could be obtained using positrons. In this paper we examine the possibilities for imaging single molecules with positrons and for l...
