title: Signatures of prelocalized states in classically chaotic systems.
abstract: We investigate the statistics of eigenfunction intensities P(/psi/(2)) in dynamical systems with classical chaotic diffusion. Our results contradict some recent theoretical considerations that challenge the applicability of field theoretical predictions, derived in a different framework for diffusive disordered samples. For two-dimensional systems, the tails of P(/psi/(2)) contradict the results of the optimal fluctuation method, but agree very well with the predictions of the nonlinear sigma model.
