{\pi ^0}

at rest decays into

2\gamma

rays,

{\pi ^0} \to \gamma + \gamma

. Then which of the following can happen

View answer and explanation

Correct option: B

The two

\gamma 's

move in opposite direction

Option B (The two γ's move in opposite direction) is correct because momentum must be conserved, and since the π⁰ is initially at rest, the two photons must have equal and opposite momenta.
