Two mechanisms for the $\pi_1$ ($J^{PC}=1^{-+}$) hybrid meson decay processes$\pi_1\to\eta\pi,\eta'\pi$ are investigated. These mechanisms are applied to$\phi\to\eta\gamma,\eta'\gamma$ and $J/\psi\to\eta\gamma,\eta'\gamma$ decays toillustrate the validity of the decay mechanisms and to obtain independentinformation on the coupling of $\eta,\eta'$ to quark and gluonic operators.  From this information, we find that$\Gamma(\pi_1\to\eta\pi)/\Gamma(\pi_1\to\eta'\pi)$ is substantially differentin the two decay mechanisms, and hence future experimental measurements of thisratio will provide valuable information for substantiating the hybrid nature ofthese states and for determining the mechanism for these hybrid decays.Comment: 5 pages, revtex, 1 eps figure embedded in manuscript.
