Abstract. We consider a family of Schr\"odinger operators depending on a real parameter and prove that the a.c. spectrum covers the positive half-line for almost every value of the parameter. The potentials in this model are neither fast decaying, nor they are oscillating or have derivatives with respect to the angular variable.
