Abstract The pure lattice SU(2) gauge theory is studied with a single plaquette EXP action by means of Monte Carlo simulations using a 120 element subgroup. The ratio of the lattice Λ-parameter to the square root of string tension is (1.02±0.05) x 10-4, which is much less than that of Wilson's action. But at finite temperatures, the deconfinement transition point is found to be TC = (210±28)MeV, in good agreement with Wilson's one.
