✦ Synopsis

We consider theoretically the exchange coupling for independent heavy excitons in both weakly and strongly conÿning quantum wires. We discuss di erent contributions for the spin depolarization in the presence of spin-conserving scatterings and show that localization e ects weaken the spin depolarization rate.
