We solve the semiclassical Einstein equations for the static spherically symmetric case. Using expressions for the renormalized 〈Tμv〉, we study the effects of the back reaction on black hole spacetimes at the one-loop level. Two different situtaions appear depending on the graviton-matter balance. If matter is relevant, the temperature is increased and thus the lifetime decreased from their standard values TH= 1 8πMand τH=CM3. If the graviton is dominant T is smaller than TH and more important, it can have a maximum at M≈Mp and then go to zero. The connection with string theory is discussed. © 1988.
