Using Tadpole-improved lattice action, the low-lying glueball spectrum of t
he pure-gauge SU(2) theory is calculated on an anisotropic lattice. The res
ults of m(0(+)), m(2(+)), and m(0(-)) are consistent with that for the Wils
on action on much larger lattices. This shows the advantage of using the co
arse, anisotropic lattice to calculate the glueball masses.
