A computational study was made for the group SU(2) based on multihistogram methods. It was found that the excitation expectation for a sufficiently extended thick vortex at large β is essentially unity. This feature was found to be responsible for maintaining the confining phase in SU(N) gauge theories even at weak coupling.
