We have measured the cross-section ratios of helium induced by Cq+ and Oq+ (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 ...

The values of direct double- to-single ionization ratio R of helium atoms induced by C^q+, O^q+ (q = 1 -4) ions at incident energies from 0.2 to 8.5MeV are measured. Based on the existing model (Shao J X, Chen X ...

We investigate angular distributions of the transmitted 60 keV and 120 keV O^3+ ions through nanocapillaries with 50hm diameter and 10μm length. The experimental results are in agreement with the 'guiding effect' ...
