Angle resolved energy correlated coincidence electron spectroscopy of solid surfaces.
Physical Review Letters 75, (12),pp 2424-2427 Springer-Verlag, (1995)
We report on the first measurements of the angle resolved energy distribution of correlated electrons created in single scattering events by low energy (E/sub p/=14-25 eV) electrons. We combined coincidence and time-of-flight techniques to measure simultaneously energies and momenta of both scattered electrons of the correlated pair. The measurements were performed in the backscattering geometry on a single crystal W(100) and a thin film of LiF. We found that the most probable energy distribution of electron pairs corresponds to a constant sum of energies of both electrons.
