Angular distributions of $\ensuremath{\alpha}$ particles emitted in the reaction $^{197}\mathrm{Au}(p,\ensuremath{\alpha})$ have been measured for proton energies in the interval 20-42 MeV. From the analysis of backward-angle spectra the statistical contribution to the reaction has been evaluated. Statistical theory appears to be able to predict the absolute value of this contribution. The analysis is consistent with the results one obtains from the study of ($p,xn$) reactions in heavy nuclei.
