This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


Table 3166 lists the main characteristics (energy loss and scattering semiangle) of the four most common energy-loss processes when an incident electron beam is interacting with materials. However, in general, the intensities of all the energy-loss processes decrease with increase of scattering semiangles θ.
