Abstract
We consider quantum cosmology for some scalar-tensor theories of gravitatio n in the case of homogeneous and isotropic cosmological models. We present quantum solutions corresponding to cosmological term: (i) lambda(phi) = 0 a nd (ii) lambda(phi) = 3q phi. In the first case we find a solution that can be interpreted as a quantum wormhole since it satisfies the Hawking-Page r egularity conditions. Also, we obtain the WKB approximation.
