摘要：
The cross sections for single-electron loss (SEL), single-electron loss associated with single ionization (SELSI) and single-electron loss associated with double ionization (SELDI) in collisions of lithium-like ions B2+, C3+, N4+ and O5+ with helium atom in the energy range from 20 to 900 keV/u were calculated by considering the distribution of both target and projectile electrons based on the Bohr-Lindhard (B-L) model. The calculated results were compared with the available experimental data. The analysis shows that the heavier the ion, the smaller the impact parameter for a given process and the impact parameters for SEL, SELSI and SELDI decrease successively for a given ion.
