Abstract
The influence of the heterointerface on the energy spectrum of shallow and deep centers is considered. Formulas are obtained for broadening of the impurity-center energy and the electron lifetime in the quasistationary state. The corresponding analytical formulas obtained in other works are refined. It is shown that in this case the effective radius of a shallow center is not its Bohr radius rB, but 2.5rB.
