Abstract：
The vacuum state of (2+1) dimensional SU(2) lattice gauge field theory is investigated. The general expressions of the parameters (μ₀ and μ₂) of the continuum vacuum wave function are derived.The numerical results which come from the improved Hamiltonian and the truncated eigenvalue equation method display a good scaling behavior in the deep weak coupling region.
