The mean excitation energy (MEE) for Al, Ti, Fe, Cu and Ta has been determined experimentally by the Landan equation, which describes the most probable energy loss of electrons in the incidence direction, and the results are consistent with the values given in the literature. These provide a quick, easy and accurate evaluation method for the experimental MEE.
