Delocalizations of the A and С excitations of a mercury-like ion in the "bismuth" center of BaS-Bi phosphors at 80°K is investigated by considering the characteristics of a photostimulates scintillation. It is found that excitations in the A band are not accompanied by delocalization of impurity-electron excitations, whereas excitation in the С band is accompanied by delocalization involving "memorization" of the ionization location upon election breakoff.
