Low-energy secondary-electron spectroscopy of molybdenum

A theoretical interpretation of the fine structure of the secondary-electron emission spectra and the secondary-electron emission coefficient is given for molybdenum. The calculations are carried out with allowance for the energy dependence of the energy-band broadening, the electron-electron and electron-plasmon contributions to the state occupation function, and the isotropic component of the current from surface-scattered electrons. It is shown that the fine structure of the secondary emission spectra and the secondary emission coefficient is mainly attributable to the electronic structure of the final states into which electrons enter and from which electrons are emitted.
