The electron vacuum fluctuations measured by (ψψ) do not vanish in an externally applied electric field ε. For an exactly constant field, that is for vacuum fluctuations in presence of a constant accelerating force, we show that (ψψ) has a Boson-like structure with spectral state density tanh-1(E/m) and temperature TM = eε/mπ = a v/π. Considering the vacuum fluctuations of 'classical' gyromagnetic ratio g = 1 particles we find Fermi-like structure with the same spectral state density at a smaller temperature T1 = a v/2π which corresponds to the Unruh temperature of an accelerated observer.
