Resonant intensification of single-phonon scattering of light; excitation profiles of quasilocal modes in the KBnMnO4- crystal
Rebane L. A., Blumberg G. E., Fimberg T. A.
The excitation spectra of that resonant Raman scattering of light by phonons of a KBr crystal which is induced by an impurity molecule Mn04~ have been measured for the first time. The results show that low-symmetry phonon modes participate in a Jahn-Teller effect in the T2 electronic state of the impurity.
