摘要：

The effect of a random perturbation is investigated for a Hamiltonian with systematic degeneracies. It turns out that the influence of the degeneracies remains significant under a perturbation. In,particular, the eigenvectors manifest specific patterns when the perturbation produces all characteristics of quantum chaos for the spectrum.
