Abstract
An analytical approximation of [T-mu nu] for a quantized scalar field in a static spherically symmetric spacetime with a topology S(2)xR(2) is obtaine d. The gravitational background is assumed slowly varying. The scalar field is assumed to be both massive and massless, with an arbitrary coupling xi to the scalar curvature and in a zero temperature vacuum state. It is demon strated that for some values of curvature coupling the stress-energy has th e properties needed to support the wormhole geometry.
