Abstract

Antihydrogen formation in the laser-assisted positronium- an tiproton collision is investigated in the first Born approximation. It is found that the differential cross section for a geometry of laser polarization paralle l to the incident direction of positronium is lowered in small angular range, bu t enhanced in medium angular range. When the laser polarization direction is per pendicular to the incident direction, the cross section enhancement obviously at medium angles is notable.
