Homework Help: Spin and parity predictions from kaon decay

  1. Mar 17, 2012 #1
    Hello ,

    1. The problem statement, all variables and given/known data

    I'm supposed to find restrictions for the spin and parity of the Kaon from the the following decay : [tex] K^0 \rightarrow \pi^0 \pi^0 [/tex]

    2. Relevant equations
    The only thing I know is that [itex] \pi^0 [/itex] spin-parity is [itex]0^- [/itex]

    3. The attempt at a solution
    I said that the spin of the Kaon is just the relative angular momentum L of the two pions and that the parity must be (-1)L+2. But this doesn't give any restrictions and I don't know what to do next.
    I hope someone can help me. Thanks
