  We study the topological content of the SU(3) vacuum using a method based on
RG mapping developed for SU(2) gauge theory earlier. RG mapping, in which a
series of APE-smearing steps is done while tracking the observables, reduces
the short range fluctuations in the gauge fields while preserving the long
structure. This allows us to study the instanton size distribution and
topological susceptibility for SU(3) gauge theory. We arrive at a value for the
topological susceptibility ${\chi}^{1/4}$, of 203(5) MeV. The size distribution
peaks at $\rho = 0.3fm$, and is in good agreement with the prediction of the
instanton liquid models.
