Title:	Comment on the plasmon model for image-potential-induced surface states
Author:	Barberán Falcón, Núria; Echenique, Pedro M.
Other authors:	Universitat de Barcelona
Abstract:	Calculations of the binding energy of bound positron states in metal surfaces, with explicit inclusion of plasmon dispersion and single-particle effects, are presented. The binding energy is greatly reduced with respect to the undispersed case.
