A Green's function technique is developed to study the Ising model with a transverse field. The order parameter and the longitudinal susceptibility are determined. The critical exponents β and γ are numerical calculated for different dimensional lattices. Using the scaling laws, α, δ, η, and v are obtained too. The critical exponents are in very good agreement with other theoretical results and with the experimental data.
