摘要：

Total energy distributions of field emission electrons from a single crystal [310]-oriented tungsten tip have been measured at temperatures of 80 and 300 K and in the emission current region from 10(-8) to 10(-6) A. We have used a high resolution field emission spectrometer computer-controlled by a low-noise power supply developed in this experiment. The main part of the observed distributions agree with the theoretical ones calculated on the basis of the Fowler-Nordheim theory, while discrepancies have been observed in two regions.
