This synchroinisation seam indeed plausable and after studying the two atom molecule models in GUTCP I think one can say that the screening effect than we know enhance fusion rate is not due to
decreased repulsion, but a syncronisation of the magnetic moments that aim one atom against the other. For one atom to hit another atom you need excess kinetic energy to keep straight paths and
not deflect. WIth screening and hence the aiming the hit is plauseble at lower energy levels.
