摘要：

Displacement cascades have been generated in ruthenium, a high melting-point hexagonal metal with a c/a ratio of 1. 58, by irradiation with heavy ions having a range of masses and energies. A detailed transmission electron microscopy analysis of the vacancy loops formed by cascade collapse has shown that four distinct sets of loop geometries are present. From determination of the loop size distributions, estimates have been made of the prism and basal intrinsic fault energy. The possible reasons for the formation of the higher-energy faulted basal loops and their apparent loss during examination are considered.
