The simultaneous emission of two electrons from W(100) after excitation by a normally incident primary electron is studied as a function of the primary electron energy (10-22 eV relative to the Fermi level) and emission angle. We found that the. coincidence rate as a function of the primary electron energy had a low-intensity tail in the region below 18 eV with an energy threshold at 11.5-12 eV. The most probable angle between two scattered electrons was found to be about 80 degrees at 20.6-eV primary electron energy. The maximum sum energy of correlated electrons is found to agree with the energy conservation law limit. Experimental results are in fair agreement with calculations based on a two-parabolic-band approximation.
