"A high-energy photon creates a pi+ pi- pair." ?
"A high-energy photon creates a pi+ pi- pair. What is the minimal frequency of the photon?" (+ other side questions)
E = hf
E = mc²
Well superficially it looks very easy, just taking hf = 2mc² with m the mass of a pion, but... How can one photon create a pair, this is not possible. Or am I missing something?
