The multiple scattering-Xa molecular cluster model is used to study the A center in silicon. We show that this center can be created by Jahn-Teller effects over substitutional oxygen impurity in the lattice. Our defect model provides a consistent explanation for the EPR experimental results obtained for the Si-A center.
