On the possibilities to study the exotic state $1^{-+}$ in the experiments on photoproduction of the $\pi \eta$, $\pi {\eta }^{\prime }$ systems

I. G. Aznauryan

We show that in photoproduction experiments there are propitious conditions to study the exotic state $1^{-+}$ in the $\pi \eta$ and $\pi {\eta }^{\prime }$ channels. We show that for unpolarized photon b…
