WebMay 9, 2024 · Most of the backscattering takes place near the end of the primary-electron range. The SE2 yield can be written as: δ(SE2) = βηδ, where β is a factor (often in the range 2–3) that allows for the fact that backscattered electrons have lower mean energy than the primary beam and some of them pass through the surface region obliquely [ 20 , 21 ].
