Inspired by Sutherland's work [Phys. Rev. Lett. 74 (1995) 816] on the detection of bound spinwaves, we propose that bound electron states can be detected from the dependence of interactingelectron systerns on the Aharonov-Bohm flux in the 'extended zone' schexne, where the electronpairing halves the original period of Y. flux quanta in a system of linear size N.. Along withthe Bethe ansatz analysis, a ntrmerical implementation for keeping track of the adiabatic flow ofenergy levels is applied to the attractive/repulsive Hubbard rnodel and the t-J ladder.
