The transverse:field Ising model is solved within the scheme of the generalized mean·field method earlier proposed by the authors. The uncompatibility between the self.consistency condition and the thermal equilibrium is corrected through the introduction of a correlated mean·field, realized by a virtual· field parameter. Numerical results are discussed in detail, from which the specific heat and the transverse·field/critical·temperature phase boundary diagram are derived.
