Share the Energy

Watch a neutron decay: an electron and an antineutrino fly out, sharing the available energy. Because the split varies, the electron energy spans a continuous range up to a maximum.

Mission Predict the range of energies with which beta particles are emitted. Streak 0Best 0
Beta particles from a given decay are emitted with:
processn → p + e⁻ + antineutrino
this electron energy
The energy is shared with the antineutrino, so the electron energy varies up to a maximum: a continuous spectrum.
