Synopsis Cross-sections computation of the formation of antihydrogen’ atoms or ions resulting from two consecutive collisions between positronium atoms and antiprotons is a central issue of GBAR’s experiment. In [2] cross-section calculations using a perturbative approach, have been undertaken, for the charge exchange three- and four-body reactions (1) and (2). In the present study, we investigate the influence of a laser field on these two reactions. We show that under special irradiation conditions, antihydrogen’ atom or ion formation cross-sections may be increased by the presence of the laser field.
