Abstract
By means of a high-statistics Monte Carlo simulation, Fisher scaling is studied for pure SU(2) and SU(3) lattice gauge theory. In both cases is found to be the lowest state above the vacuum, and the glueball mass ratio is slightly larger than 1. For SU(2), Monte Carlo data smoothly continue the analytic small-volume calculation towards the infinite-volume continuum limit. New results for the ratio between the square root of the string tension and the mass gap are also reported.
