================================================================================= | ||||||||
In electron diffraction, since the radius of the Ewald sphere increases with decreasing electron wavelength λ, the value of G of a diffraction spot for any given orientation will increase as the accelerating voltage is increased. Therefore, it becomes difficult to observe the diffraction spots with high H K L values and the HOLZ rings at low or intermediate voltages.
