Experimental cross sections for water ionization due to the impact of light ions—A review.

This work is a short review on the experimental cross sections for water ionization due to the impact of light ions (Z ≤ 6), including related processes such as electron capture and water molecule fragmentation. These cross sections are crucial in studies dealing with the biological effects produced by the impact of ions on living beings. Physical interpretations of the experimental results are also provided. • Experiments on ionization and charge transfer in water impacted by light ions are reviewed. • A brief theoretical introduction is offered for supporting the analysis. • A profound physical discussion of the results is carried out. • One- and two-center effects in secondary electron emission are discussed. • The relation of these effects and First-Born and CDW approximations are commented.
