We estimate the relative branching ratio of $\sigma$ to 2$\pi$ for the decay of the $\Psi'(2S)$, which we have found to be a mixed charm and hybrid charmonium meson. The external field method and correlators from a previous calculation are used to estimate these decays. We find the $\sigma$ to 2$\pi$ branching ratio for $\Psi'(2S)$ to the $J/\Psi(1S)$ decay to be 0.98, in agreement with an experiment at IHEP-BES.
