    dear all,
    pion^0 particle has a spin 0, but its decayed gamma has spin of 1. why this process could happens?
    Thanks in advance.

    The spin of a photon is one, but it also has a direction. The spins of the the two photons are antiparallel, so total spin angular momentum is zero, as was the pion.
