By J.W. Negele, Erich W. Vogt
This quantity includes 3 overview articles written by means of a few of the main specialists on the earth and bearing on 3 various difficulties of serious present curiosity for nuclear physics. One article bargains with the starting place of spin within the quark version for neutrons and protons, as measured with beams of electrons and muons. one other offers with the present facts for liquid-to-gas part transitions in relativistic collisions of nuclei. The 3rd bargains with the very strange bands of strength degrees of very excessive spin that are came upon whilst nuclei in attaining a truly excessive rotation.

In this case one could expect the appearance of predicted by Mottelson "compound", or "ergodic", b a n d s where the energy and angular m o m e n t u m flows in the deexcitation process proceed along specific chains of compound states, without significant branching. This idea is supported by shell model calculations of nuclear spectra and transition probabilities as well as the behavior of pairing in different J classes 1 7 . A similar effect is possible in pairing rotation where the "band" consists of ground states of neighboring nuclei.
Unique and the dynamical mixing plays no role. The random character of the wave function for Jo = 0 is confirmed by the direct analysis of the distribution of its components in the seniority basis. The fully paired component of seniority zero is distributed according to the RMT predictions. We come to the conclusion that elements of the ordered spectra of finite Fermi-systems are in fact stipulated by the rotational invariance and the presence of many competing quasi-random paths of angular momentum coupling.
