In zero field we find a large residual linear term $\\kappa_0/T$, more than 40% of the normal-state value. At low field, the $\\kappa_0/T$ shows an $H^{1/2}$ dependence. These provide strong evidences for nodes in the superconducting gap of Ba(Fe$_{0.64}$Ru$_{0.36}$)$_2$As$_2$, which mimics that in another isovalently substituted superconductor BaFe$_2$(As$_{1-x}$P$_x$)$_2$.
