SELF-ORGANIZATION IN THE NUCLEAR SYSTEM .2. FORMATION OF A NEW ORDER

The information entropy of the atomic nucleus is calculated from the wavefunctions of the resonance states. The transition from low- to high-level density is traced as a function of the coupling strength between the discrete nuclear states and the environment of decay channels. In the critical region of the coupling strength where a redistribution inside the nucleus takes place, information entropy in relation to the discrete states of the closed system is created. Beyond the critical value, a few relevant short-lived modes exist together with long-lived noise. This result is in full correspondence to the maximum information entropy principle of synergetics formulated by Haken. The noise is characterized by disorder expressed by a large information entropy while the relevant modes have a high order and take, correspondingly, a small part of the information entropy of the whole system. The entropy excess accompanying the formation of the new order is used inside the system for creation of noise. Further, the noise is not structureless and the corresponding information entropy is smaller than its maximal value.
