One of the two fundamental dynamical Jahn-Teller problems in point-symmetry surrounding, the T–t problem, is handled by means of a non-linear canonical transformation. The latter is established by analogy to the doubly degenerate problem, where the corresponding tranformation is shown to be quasi-exact. Combinatorial as well as series expansion methods are presented. Pronounced resonance effects are found for the zero, one, and higher phonon lines. This reflects the fact that the effective… CONTINUE READING
