Piezospectroscopic effect in local and resonant oscillations connected with a degenerate electronic state of an impurity center in a crystal
Vasil'ev A.V. , Natadze A.L. , Ryskin A.I.
We investigate the piezospectroscopic effect on a number of lines of the electron-vibrational band *A2—>*T\[*F\ in a ZnS-Co crystal. We show that the resonant and gap oscillations that appear in the spectrum are due to linear interaction of an orbitally degenerate 4T{ term with degenerate oscillations.
