Description
We present the Born amplitudes for the pi eta photoproduction on the nucleon. These amplitudes and the corresponding partial wave amplitudes are essential for the description of the photoproduction of isovector resonances with masses below 2 GeV. Some of these resonances, in particular $a_0(980)$ and $a_0(1450)$ are believed to have a substantial mollecular admixture. These mollecular states can be effectively described in terms of the final state interactions. The model can also be applied to the photoproduction of the elusive
$\pi_1(1400)$ meson which decays to the pi eta system.
