Field-induced electron-Ion recombination: A novel route towards neutral (Anti-)matter

Phys Rev Lett. 2000 Apr 24;84(17):3799-802. doi: 10.1103/PhysRevLett.84.3799.

Abstract

We present a novel approach to the preparation of neutral (anti-)matter. The scheme is based on recombination of a free electron and an ion, and can be considered as the inverse of pulsed field ionization. We have obtained promising results on rubidium: at low densities already efficiencies of 0.3% were obtained. This is orders of magnitude more than has been achieved in previous recombination studies.
