A procedure for distinguishing the regions of emission of laser-plasma jet multiply charged ions is developed and realized. With the aid of the procedure, the presence of the transverse emission of laser-plasma jet multiply charged ions is found experimentally and its parameters are studied. The size for the effective region of emission of laser- plasma jet multiply charged ions is determined experimentally. It is found experimentally that the main process leading to the decrease of the multiply charged ion yield for a surface is the nonresonant ion recharge on atoms. Within the model concerned, the spray of multiply charged ions over the surface of a massive sample was predicted and found experimentally.
