nuclear physics - Can neutrons be synthesized purely from protons and electrons?


Can neutrons be synthesized purely from protons and electrons?



Note: I'm looking for reactions that do not require neutrinos or any particles besides just protons and/or electrons as reactants.



Answer



Yes, they can be. The production of neutrons by deep inelastic scattering of electrons on protons was studied in HERA experiments in the 90's. No neutrino needed, at least not as one of the colliding particles. Here are some links:
