[Auszug] Fig. 1. Variation of scattering cross-section of carbonaceous samples for 50-kV. electron beam Considering the samples to be composed mainly of carbon, the scattering cross-section per atom is a = AS N, that is, 2 x 10~23.S cm.2, and the same curve (1) represents a versus a, with suitable change ...
