Abstract: We measured the cross-section ratios of helium induced by Cq+ and Oq+ （q=1—4） produced by the 2×1.7 MV tandem accelerator of Lanzhou University in the energy range from 20 to 500 keV. We obtained the two-dimensional spectrum by employing coincidence method combined with the MPA-3 data acquisition system. Thus, we obtained the ratios of direct ionization, projectile capture electrons and projectile loss electrons to the total cross-section which are denoted by of Rdirect， Rcapture and Rloss in this paper. A qualitative explanation of the competitive relation of the three reaction-channels and the emperical laws of the three reaction channels are separately presented.
