The effect of a disclination upon the energy spectrum of a free particle which was confined so as to move between 2 concentric cylindrical shells was studied. It was seen that the change in topology which was caused by the defect produced an analogous effect to that of the bound-state Aharonov-Bohm effect in condensed matter.
