Abstract
Monte Carlo calculations of secondary electron emission from Cs3Sb have been made for primary electron energies in the range 0.6–10 eV. All parameters in the model were determined by analysis of independent photoelectric emission experiments. Good agreement is obtained between calculated and measured secondary emission yields. Structure in the measured yield related to the threshold for electron pair production also shows up in the calculations. The results indicate that the semiclassical three‐step model for photoelectric emission (excitation, scattering, and escape) also provides an accurate description of secondary electron emission.
