This paper proposes a novel mechanism for baryon creation through lepton fusion in diverging magnetic fields, potentially explaining the temperature anomalies observed in Jupiter's polar auroral regions. Building on the half-photon electron model, we demonstrate that electron-positron-electron triples can facilitate proton-to-neutron conversion through half-photon transfer, producing free neutrons with subsequent beta decay. This mechanism provides a natural explanation for the observed electron-proton temperature asymmetry, quasi-periodic auroral pulsations with characteristic timescales matching neutron decay lifetimes, and the excess energy radiation from planetary magnetospheric cusps. The process requires three essential components: hydrogen molecules to provide spatially-localized electron pairs, thermal positrons from pair production, and diverging magnetic field gradients to induce spin-flip transitions. We derive the energy budget showing available electromagnetic potential energy of approximately 1.44 GeV at quark length scales, substantially exceeding the neutron rest mass of 0.94 GeV. The predicted spatial-temporal signature consists of expanding emission rings propagating at neutron thermal velocities with exponential brightness decay matching the neutron half-life of 880 seconds. This work establishes testable predictions for both laboratory beam-line experiments and astronomical observations, potentially revealing a new pathway for nuclear transformation mediated by electromagnetic field structures in curved spacetime.
