The possibility of heavy ion additional acceleration in laser beams is investigated. The main observation is the existence of a big variety of acceleration modes due to many fitting parameters even for only one Gaussian beam and for crossed ones even more so. An essentially non-monotonic dependence of energy gain on relevant variables such as initial velocity or pulse duration is found which makes the search for the most effective acceleration modus very complex. There is a threshold level for the intensity (∼ 1025 W/cm2 ) when the ion moves in the capture mode in one direction. The crossed beam scheme is at least three times more effective than one beam scheme within the considered range of parameters. However, such a scheme works only for certain phasing of the beams which is difficult to provide at such field intensity. Moreover, the other nonlinear effects as pair creation and vacuum polarization can also be active.
