The Production of Ultra-low Momentum Neutron on Metallic Hydride Surfaces by Heavy Electron

The collective motion of protons on the metallic hydride produces strong local electric fields that renormalize electron mass, increasing the mass of the electron known as the heavy electron. The protons can capture heavy electrons to yield extremely low momentum neutrons plus neutrinos. In this study, we present the physics of the heavy electron capture process with the particle-in-box model approach and the production of ultra-low momentum neutrons. The heavy electron is assumed as a classical particle in a 3D box with the L dimension to thoroughly comprehend this emerging phenomenon. The length range of the box was estimated using Campton wavelength and the minimum electron energy to provide the capture settings. According to the calculations, a possibility of electron capture interaction is observed in 400 to 910 femtometers. The energy dependence of the electron, proton, and generated neutron was determined based on the box length to pursue the interactions. Finally, we calculated the ratio of the production power of the interaction of the ultra-low momentum neutron with the surrounding protons (P_n) to the capturing power of the heavy electron and the proton ( P_ep ) in terms of the box length. We observed that P_n/P_ep value for L> 400 fm is above 1, which is the desired value.
