Ratio between the energy-loss spectrum in coincidence with secondary electrons and the normal energy-loss spectrum for thin carbon films in the carbon K-edge region.

Abstract

In experiments similar to previous work we have investigated the ratio between an energy-loss spectrum in coincidence with secondary electrons and a normal electron energy-loss spectrum in the energy-loss range 0-500 eV. We obtained similar results in the low-loss region, but in the high-loss region different results were obtained. The ratio of the coincident and normal energy-loss spectrum is the product of the probability of an energy-loss event emitting one secondary electron and its detection probability
