ANTIHYDROGEN FORMATION IN LASER-ASSISTED POSITRON-ANTIPROTON SCATTERING

Antihydrogen formation in the laser-assisted positron-antiproton (nonr elativistic) radiative recombination is investigated. The state of inc ident positron is given by the Coulomb-Volkov wave function. The pertu rbative dressed wave function of the atom is obtained in the soft-phot on approximation. Our calculation shows that for a geometry of laser p olarization parallel to the incident direction, the formation cross se ction of antihydrogen is greatly reduced. Especially at high impact en ergy, the reduction is remarkable.
