Probabilities of the various types (summarized in Fig. 2[link]) of a 200 keV electron scattering in a hydrated protein sample. For other electron energies the horizontal axis has to be rescaled by a factor of 0.4835(c/ν)2. For 100 keV, 120 keV, 300 keV, 500 keV and 1000 keV, the rescaling factors are, therefore, 0.62, 0.71, 1.25, 1.42 and 1.83, respectively. So, for instance at 100 keV, the peak of Pkin(z) occurs at a thickness of approximately 45 nm (0.62 × 70 nm), instead of at 70 nm.
