Abstract
We calculate the order parameter m(e) and the root-mean-square order p arameter m(rms) of an exactly soluble model of a structural phase tran sition. In this model classical and quantum critical fluctuations depe nding on the temperature T and the dimension of the space d are presen t. For the ratio r (d, T) = m(e)/m(rms), we obtain r (d, T) = square-r oot n. This result does not depend on the quantum and/or classical flu ctuations.
