Abstract

A new model for the formation of ion damage tracks in dielectric solids permits the dimensions of the microscopic structure of the latent tracks to be calculated. In this model the formation of the damage is initiated at separate points along the track by the Auger decay of vacancies produced by the ion in inner electronic shells of atoms of the insulator. Each decay produces an intense, localized source of charge, whose interaction with the more uniform ionization of the loosely bound electrons along the ion's path causes the atomic motion that results in the damage. Available data on cellulose triacetate and mica are in excellent agreement with the predictions of the model.

Additional Information:© 1984 Published by Elsevier B.V. Received 3 October 1983. I wish to thank Dieter Albrecht and Reimar Spohr for conversations about their data that were extremely helpful in making these comparisons with theory. Just a this manuscript was being submitted for publication the author has discovered that the idea of Auger decays serving as the initiation sites for track damage was mentioned in a publication by M. Maurette in 1970 [18). Subsequently. the description of the damage distribution along latent heavy ion tracks in terms of the K-shell ionization cross section was discu sed in the unpublished thesis of J.P. Duraud (19]. Neither of these authors uses this mechanism to calculate the dimensions of latent damage tracks, which is the main purpose of the present publication. The author recommends to the reader these original references.
