Yes, in near vacuum with both collisional entities essentially free, only at very high energies is coulombic repulsion overcome. By dimensional restraints these activation energies can by greatly lowered. The question may be how can the restraints be simultaneously and oppositely applied to both fusile entities down to a femtometer scale w/o disrupting those restraints. Surface associated phenomena of several sorts may be a route to such restraints. Keeping in mind that the nano to picometer scale of electronic orbitals and atomic structure at say solid to gas or solid to liquid interfaces over sustained times might only contribute up to some limit at lattice or surface dissociation energies. Pulses offer the opportunity to convert lattice inertia into a virtual sub-picometer "vise" to enable fusion. Shielding by oppositely charged entities can greatly lower the collisional barrier, especially when the collisional matrix/interface is nearly static. There are many other categories of surface associated "focusing" phenomena which can also contribute. So besides phase interfaces, there are easily impressed field gradients, chemical and electrochemical discontinuities, as well as surface confined electromagnetic transmission phenomena such as the "skin effect" and surface plasmon resonance. All such have been reported or speculated to be associated with changes in effective mass of electrons-- and likely also, and perhaps not accidentally, with LENR / CANR / LANR / CF AHE reports.
The electrons are confined in dipole oscillation and they function to comfine heat in micro cavities so that the heat can be converted to magnetic flux lines. In order for entanglement between photons and electrons to occur, the electrons and the heat photons must stabilize at the same energy so that entanglement between them can occur.
