• The properties of the atomic nucleus are investigated from the point of view of selforganization. The nucleus is described as an open quantum mechanical many-body system embedded in the continuum of decay channels. The information entropy is calculated in relation to two different sets of basic wavefunctions: I_β is obtained from the wavefunctions of the resonance states in relation to the shell model states and I_γ is calculated by means of the partial widths in relation to the decay channels. Both information entropies are calculated as a function of the coupling strength of the nuclear states to the continuum of decay channels. The I_β characterize the mixing of the wavefunctions of the resonance states in relation to the shell model basis while the I_γ are connected with the irreversibility of the scattering process. As a result, neither I_β nor I_γ are a proper measure of quantum chaos. Additional information on lifetimes and level density is necessary.
