摘要：

It is well known that the presence of a constant electric field in Minkowski space induces pair production from vacuum. The population ratios of pairs of different mass so produced is Boltzmann in character, the temperature being a/2-pi; where a is the acceleration due to the field. These ratios are maintained subsequent to production when the interaction of the charged particles with the vacuum of neutral radiation is taken into account, i.e. particles are born in a thermal equilibrium which is maintained dynamically. We attempt to explain this consistency in terms of the tunneling of the wave function behind the classical turning point.
