Abstract
We consider dependence of the critical fluctuation operators on the ra te of interaction decay for an exactly soluble model of the quantum an harmonic crystal of ferroelectric type. The critical exponents for the abnormal behavior of the displacement and momentum fluctuation operat ors on the critical line are calculated explicitly.
