We compute the topological susceptibility for the SU(3) Yang‐Mills theory by employing the expression of the topological charge density operator suggested by Neuberger’s fermions. In the continuum limit we find r04χ = 0.059(3), which corresponds to χ = (191 ± 5 MeV)4 if FK is used to set the scale. Our result supports the Witten‐Veneziano explanation for the large mass of the η′. Comments on the large‐volume distribution of the topological charge are presented.
