SUMMARY
The minimum energy required for the reaction e + p -> neutrino + neutron is determined by applying energy and momentum conservation principles. The kinetic energy of the proton is negligible compared to its rest mass energy, while the electron's kinetic energy is significant. The borderline case occurs when the neutrino energy approaches zero, necessitating the electron to possess sufficient energy to overcome the attractive force between the electron and proton. This scenario can be likened to calculating escape velocity in gravitational contexts.
