Abstract
The total energy distribution (TED) of field emitted electrons has been measured for [012] direction of tungsten monocrystal in temperature region from 78 K to 950 K. To compare measurements with the free electron (FE) theory the parameters of FE equation of TED have been calculated by extrapolation of experimental results to the zero temperature. The explanation of obtained results has been proposed, taking into account the electron scattering phenomena of electrons supplied to the surface during the emission. Characteristic features of s→ d and s→ s scattering in transition metals described by Mott's theory have been indicated by TED curves for the [012] direction. The Nottingham effect measured for [012] has been discussed as well.
