SUMMARY
Inverse beta decay is forbidden for a free proton due to energy conservation constraints. The reaction p -> n + e(+) + v cannot occur because the mass-energy of the initial state (the free proton) is greater than the combined mass-energy of the final state (the neutron, positron, and neutrino). This results in a negative Q value, making the process energetically unfavorable and thus prohibited.
