Structure of zero-phonon line of Jahn-Teller system for weak vibronic coupling with pseudolocal oscillations
Gnatenko Yu.P., Rozhko A.Kh.
The structure of the zero-phonon line (ZPL) has been observed for the first time for an impurity center in a crystal in the case of an Al—>T2 transition, which can be interpreted as being due to the Jahn-Teller effect in the presence of vibronic coupling with pseudoscalar oscillations.
