    Graduate \eta\to\pi^0\gamma decay (Why this decay is forbidden by J?)

    Decay \eta\to\pi^0\gamma is forbidden by C parity. But why this decay is also forbidden by statistics (J)? pi^0 spin is 0 photon spin is 1 But there are can be different situations with full orbital angular momentum of pi^0\gamma. J=L+S and must be 0. Look like L is 0. But why? Why we can't...
