Surf-Riding Electron States: Polarization Charge Density Effects Associated with Heavy Ion Motions in Solids

  • V. N. Neelavathi

Characterization of charged particle energy loss to electrons in condensed media in terms of polarization waves created by the particle is well known from the early work of Fermi [1], Bohr [2], and others. These polarization waves give rise to an oscillatory potential field extending behind and moving along with the particle [3]. We wish to point out that there may exist quasi-stationary states of electrons in the minima of such a field and that electrons may be captured into these surf-riding states.
