{\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

\gamma 's

move in opposite direction) is correct because momentum must be conserved, and since the pion was at rest, the photons must move in opposite directions with equal momentum.
