LATTICE ION-TRAP - CLASSICAL AND QUANTUM DESCRIPTION OF A POSSIBLE COLLISION MECHANISM FOR DEUTERONS IN METAL LATTICES

The dynamics of deuterons inside a palladium lattice around tetrahedra l sites at high deuterium concentration is studied by using both a cla ssical description and a quantum mechanical representation, and the re sults are compared. The classical representation takes advantage of th e similarity between the electrodynamic confinement of charged particl es stored in a quadrupolar radio-frequency trap and the palladium latt ice. The quantum mechanical description of the dynamics of a charged p article interacting with another charged particle within a lattice rad io-frequency trap is carried out by solving the time-dependent Schrodi nger equation with a numerical procedure. Both descriptions produce an interaction effect between the deuterons inside the metal lattice.
