Abstract

In the soft-photon approximation, the laser-assisted radi at ive recombination between a positron and a antiproton is investigated. The lase r field is treated as a classical electromagnetic field. The positron state is described by the Coulomb-Volkov wavefunction, and the dressed state of antihyd rogen in final state is a perturbative solution of the time-dependent Schding er equation. It is predicted that the cross section for antihydrogen formation is greatly lowered in the presence of...
