“…A list of some of the charge-transfer data published since 1988 is provided in Table 3. These data are largely taken from the review of Janev et al [39], the work of Kusakabe et al [40], Itoh et al [41], Rottmann et al [42], and the work that they quote. From the listing in Table 3, one can see that a majority of the available data is for electron capture by carbon ions.…”

It is widely accepted that an understanding of the detailed structure of charged particle tracks is essential for interpreting the mechanistic consequences of energy deposition by high linear energy transfer (LET) radiation. The spatial relationship of events along the path of a charged particle, including excitation, ionization, and charge-transfer, govern subsequent chemical, biochemical, and biological reactions that can lead to adverse biologic effects. The determination of spatial patterns of ionization and excitation relies on a broad range of cross-section data relating the interactions of charged particles to the molecular constituents of the absorbing medium. It is important that these data be absolute in magnitude, comprehensive in scope, and reliable if accurate assessment of track structure parameters is to be achieved. Great strides have been made in the development of this database, understanding the underlying theory, and developing analytic models, particularly for interactions involving electrons and protons with atoms and molecules. The database is less comprehensive for interactions involving heavier charged particles, especially those that carry bound electrons, and for interactions in condensed phase media. Although there has been considerable progress in understanding the physical mechanisms for interactions involving fast heavy ions and atomic targets during the past few years, we still lack sufficient understanding to confidently predict cross-sections for these ions with biologically relevant material. In addition, little is known of the interaction cross-sections for heavy charged particles as they near the end of their track, i.e., for low velocity ions where collision theory is less well developed and where the particle's net charge fluctuates owing to electron capture and loss processes. This presentation focuses on the current status of ionization and charge-transfer data. Compilations, reviews, Internet sources, theoretical models, and recent data applicable to track structure calculations are discussed.

“…al. [1] [2] had observed that the meta stable cross sections are too small to be measurable and concluded that this behavior was caused by efficient suppression of electron capture by one of the meta stable state ions due to a competing collisionally induced inelastic transition into the companion meta stable ions. Lindsay and Stebbings [3] have reinvestigated the same process to resolve this.…”
