total secondary-electron yield

symbol: σ
https://doi.org/10.1351/goldbook.09359

Total number of electrons emitted from a sample divided by the total number of electrons incident at a given energy and angle of incidence. σ=δ+η, where δ is the secondary-electron yield and η is the backscattering coefficient.

Note: The total secondary-electron yield is often simply called the secondary-electron yield. This leads to confusion with the term of that name, which is restricted to secondary electrons with energies less than or equal to 50 eV.
