Energy Dissipation by Random Collisions in Compound Target Materials

  • N. Andersen

The paper gives a brief account of our calculations on the sharing of energy between the constituents of a polyatomic, in particular a binary medium bombarded with heavy energetic ions. With a view at radiation damage and sputtering in composite targets we calculate displacement efficiencies as a function of concentration, and particle fluxes as a function of energy and concentration for a few binary compounds. Pronounced deviations from stoichiometric behavior are found when the partial stopping powers of the constituents differ from each other because of different atomic number and mass.
