Starting from an appropriate decomposition of the level density into an average and fluctuating part, we studied the energy level fluctuations of an ensemble defined by two-body random Hamiltonians. A detailed analysis of several spectrally averaged fluctuation measures shows close agreement with the predictions of the Gaussian orthogonal ensemble (GOE). This confirms earlier indications that, except for noninteracting particles, fluctuation measures are insensitive to the rank of the interaction. Further, analysis of spectra obtained from realistic nuclear interactions agrees well with the GOE indicating that specific properties of the Hamiltonian have little or no influence on fluctuations. These results, therefore, strengthen our belief in the "universality" of GOE fluctuations.

A semiclassical theory of the vibration–rotation energy transfer of fast rotating molecules is presented. The formulation is based on the same model as that of Shin's classical theory. The semiclassical theory is simpler to derive and more rigorous. We show that it necessarily gives more accurate results than the classical theory. Applications to the systems HF and DF indicate that the two theories agree reasonably well in these cases.
