Abstract
We investigate localization properties of two correlated electrons in a one-dimensional disordered system. The results found for the ''bag m odel'' in center-of-mass and relative coordinates are compared with th ose obtained earlier [Frahm et al., Europhys. Lett., 31, 1995, 169] by using particle coordinates. We show that results for the two particle localization length obtained by using the bag model depend on discret ization and/or boundary conditions (C) 1998 Elsevier Science Ltd. All rights reserved.
