| dc.description | We study statistical properties of excited levels of the E x (b_1+b_2) Jahn-Teller model. The multitude of avoided crossings of energy levels is generally claimed to be a testimony of quantum chaos. We found that apart from two limiting cases (E x e and Holstein model) the distribution of nearest-neighbor spacings is rather stable as to the change of parameters and different from the Wigner one. This limiting distribution assumably shows scaling ~$\sqrt{S}$ at small S and resembles the semi-Poisson law P(S)= 4S \exp (-2 S) at S> 1. The latter is believed to be universal and characteristic, e.g., at the transition between metal and insulator phases. | |
