Heavy Ion Damage in Thin Metal Films
A wide range of recoil energies is usually encountered in a material that is under irradiation with energetic particles. It is of considerable interest to know the damage as a function of recoil or cascade energy. Since isolated Frenkel pairs as well as cascades are usually produced together, it has been difficult to get specific information about the defect production in cascades, for example from studies of the energy dependence in charged par-icle irradiations(1,2,3). Especially in the case of electrical resistivity measurements, where only one integral quantity is measured, energy dependence measurements have not been very successful in showing the differences between cascades of various energies. The purpose of the present work was to see whether monoenergetic displacement cascades could be studied by means of electrical resistivity measurements. We can then hope to get specific information about the average displacement cascade of a well defined energy.
