Abstract
Monte Carlo results for the low-lying glueball spectrum using an impro ved, anisotropic action are presented. Ten simulations at lattice spac ings ranging from 0.2 to 0.4 fm and two different anisotropies have be en performed in order to demonstrate the advantages of using coarse, a nisotropic lattices to calculate glueball masses. Our determinations o f the tensor (2(++)) and pseudovector (1(+-)) glueball masses are more accurate than previous Wilson action calculations.
