Abstract
A numerical study of static, spherically symmetric monopole solutions of a spontaneously broken SU(2) gauge theory coupled to a dilaton fiel d is presented. Regular solutions seem to exist only up a maximal valu e of the dilaton coupling. In addition to the generalization of the 't Hooft-Polyakov monopole a discrete family of regular solutions is fou nd, corresponding to radial excitations absent in the theory without d ilaton.
