Experimental study of cross-section ratios in the collisions of Cq+ and Oq+(q=1–4) on atomic helium in strong-interaction region

doi:10.1088/1674-1056/20/1/013402

Abstract We have measured the cross-section ratios of helium induced by C^q+ and O^q+ (q=1–4) in an energy range from 20 keV/amu to 500 keV/amu, and obtained the two-dimensional spectra by employing the coincidence method combined with the MPA-3 data acquisition system. Hence, we obtain the ratios of total single-ionization cross-sections (SI, SC, SLSI, and DLSI), total double-ionization cross-sections (DI, DC, TI, SLDI, and DLDI) and cross-sections of every process (SI, SC, SLSI, DLSI, DI, DC, TI, SLDI, and DLDI), which induce the single-ionization and double-ionization, to the total cross sections respectively. The competitive relations between the reaction-channels and the experimental data law of each reaction-channel are revealed explicitly, and the qualitative explanations involved in those results are also presented accordingly.

Keywords: ion–atom collisions strong-interaction region cross-section ratios competitive relation
