Query: Mechanism of cell inactivation by different ions: Damage induction
  probabilities per single tracks   Biological effects of proton and light ion irradiations have been studied in
detail by analyzing published cell survival data with the help of the
probabilistic two-stage radiobiological model. Probabilities of single ion
tracks to induce lesions of different severity have been assessed in dependence
on their linear energy transfer (LET). The results are presented and their
interpretation in terms of $Z_{eff}^2/\beta^2$ (the effective charge over
velocity squared) is discussed.
