A pion that is moving at 0.98c, desintegrates producing two photons that form both of them the same angle with the direction of the initial pion. Find the angle and the enrgy for the photons. (Pion mass: 135 Mev/c^{2})

2. Relevant equations

E = K + m_{0}c^{2}

3. The attempt at a solution

I've found that the energy for the pion is 678,4 Mev. Now if I apply the conservation of energy, (or conservation of momentun), I'm confused, because a photon has no mass, right?

Thanks
