Summary:The entanglement of Dirac fields has been shown to decrease with increasing acceleration when a quantum state is shared between an inertial and an uniformly accelerated observer. A new form of an entangled vacuum state observed by the accelerated observer is postulated in which it is assumed that entanglement is present between the modes of the quantum field with sharp and opposite momenta defined in two causally disconnected regions of space-time. We find that this assumption does not affect the entanglement of the system.
