In the KamLAND experiment, anti neutrinos are detected via the reaction e + p e
Question:
In the KamLAND experiment, anti neutrinos are detected via the reaction ν̅e + p → e+ + n, where the target protons are at rest. Show that for incident anti neutrinos of energy Eν = 3MeV, the positron produced has an energy
E+ = Eν + mp − mn = 1.71MeV
to within an error of 1%, irrespective of the scattering angle.
