Abstract :
The authors consider the properties of O vacancies in MgO. The preliminary study shows that when additional electrons are introduced in a cluster of MgO containing an oxygen vacancy, the first two electrons partly localize in this vacancy. When more electrons are added, the implanted charge seems to be destabilized and a fraction of it seems to be moved to the surface of the cluster
