Abstract
Measurements have been made of the characteristic energy losses of 30-kev electrons in transmission through thin films of indium, indium antimonide, cadmium telluride, and zinc telluride; for comparison, the electron energy losses in antimony, cadmium, tellurium, and zinc have been reinvestigated. The energy loss spectra in these intermetallic compounds appear significantly different from a simple superposition or average of the energy loss spectra of the component metals. Some detailed interpretations of the characteristic energy losses in In and in InSb are suggested.
