Lattice Ion Trap: A Possible Mechanism Inducing a Strong Approach Between Two Deuterons in Condensed Matter

The behavior of ions confined by means of quadrupolar electrodynamic containment around palladium lattice tetrahedral sites is discussed. Ion confinement in a quadrupolar trap is known to be strongly influenced by initial conditions and trap parameters. The system studied is a lattice ion trap for deuterons, supposing they occupy the tetrahedral sites over a certain concentration. The electron motions seem to have a dominant role in the dynamics of two deuterons moving around such lattice sites. A computer simulation describes the deuteron dynamics and reveals an approach mechanism that could dramatically decrease the mean distance between two positive charges embedded in a lattice.
