## Homework Statement

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]

## Homework Equations

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

## 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
