Phys. Rev. A 72, 052702 (2005) [5 pages]Two-stage Rydberg charge exchange in a strong magnetic fieldReceived 21 June 2005; published 4 November 2005 We have performed calculations of two successive charge transfers from Rydberg states in a strong magnetic field. In the first charge transfer, a positron interacts with a highly excited atom to form positronium. In the second stage, the positronium interacts with an antiproton to give antihydrogen. For many parameters, our results are in qualitative agreement with previous calculations with no magnetic field. However, we do find that there are important changes which may affect the usefulness of the method for efficient formation of antihydrogen that can be trapped. © 2005 The American Physical Society URL:
