    "abstract": "The values of ion-atom ionization cross sections are frequently needed for\nmany applications that utilize the propagation of fast ions through matter.\nWhen experimental data and theoretical calculations are not available,\napproximate formulas are frequently used. This paper briefly summarizes the\nmost important theoretical results and approaches to cross section calculations\nin order to place the discussion in historical perspective and offer a concise\nintroduction to the topic. Based on experimental data and theoretical\npredictions, a new fit for ionization cross sections is proposed. The range of\nvalidity and accuracy of several frequently used approximations (classical\ntrajectory, the Born approximation, and so forth) are discussed using, as\nexamples, the ionization cross sections of hydrogen and helium atoms by various\nfully stripped ions.",
