摘要：

A method for determining absorption parameters, which is based on the multi-beam dynamical theory of electron diffraction, has been developed. The method is based on the sensitivity of computer calculated multi-beam intensity profiles to the values of the absorption parameters used. Experimental intensity profiles are obtained by making use of the fact that a specimen can be tilted to an orientation where multi-beam effects are important. Experimental absorption parameters obtained for molybdenum are in good agreement with the theoretical values of Humphreys and Hirsch.
