Abstract
The results of self-consistent exciton energy calculations in finite m ultiple-quantum-welIs with differing numbers of wells and varying barr ier widths are described. The calculations show that even for a perfec t system, the exciton localizes strongly in one well only. For a syste m with an even number of wells this leads to a spontaneous symmetry br eaking.
