“…Fleischer et al [12] have shown that the extent of radiation damage in dielectrics correlates better with the rate of ionization by the PKA than with its rate of energy loss, again lending support to the Coulomb explosion model. Itoh and Stoneham [13] point to evidence from work on dichalcogenides that shows track formation does not occur for electrical conductivity exceeding 10 5 Ω −1 cm −1 .…”

Abstract. Atomistic simulations are a primary means of understanding the damage done to metallic materials by high energy particulate radiation. In many situations the electrons in a target material are known to exert a strong influence on the rate and type of damage. The dynamic exchange of energy between electrons and ions can act to damp the ionic motion, to inhibit the production of defects or to quench in damage, depending on the situation. Finding ways to incorporate these electronic effects into atomistic simulations of radiation damage is a topic of current major interest, driven by materials science challenges in diverse areas such as energy production and device manufacture.In this review, we discuss the range of approaches that have been used to tackle these challenges. We compare augmented classical models of various kinds and consider recent work applying semi-classical techniques to allow the explicit incorporation of quantum mechanical electrons within atomistic simulations of radiation damage. We also outline the body of theoretical work on stopping power and electron-phonon coupling used to inform efforts to incorporate electronic effects in atomistic simulations and to evaluate their performance.

“…In practice the measured efficiency will be less than that calculated by equation (2) because: (a) The B target thickness is larger than the alpha particle range, producing a continuous distribution of alpha particle energies from 0 up to 1.5 MeV. The ionization rate of some of the low energy particles will be insufficient to leave an etchable track (Fleischer et al 1967), and some fraction of the etched tracks near zero length will not be counted. Also, tracks due to particles entering the detector surface at shallow angles will be lost during the etching process (Fleischer and Price 1964).…”

“…The use of solid state detectors, such as mica and glass, can partly overcome this problem. Fission events exceeding some critical limit of the stopping power are all registered by structural changes in the detector material and they appear after etching [12]. In addition, the use of "sandwiches" makes it possible to find out correlated pairs of fragments [1].…”
