Homework Statement
Earlier my teacher put this equation on the board,
π_0 --> γ+γ
It appears to work until you consider spin.
Homework Equations
a quick google search reveals that the spin of a photon is +1 and the spin of a pi meson is 0
The Attempt at a Solution
This appears to work for momentum, energy, charge, baryon number...
But π_0 has no spin and γ has a spin of +1.
So in essence the atomic spin starts at 0 and finishes at +2.
What am I missing?
