The relativistic spectroscopy of rotating bodies

Mutual dependencies of mass and orbital moment increase for rotating bodies of various configurations (a string with uniform mass distribution, a string with squared mass distribution or a sphere with uniform mass distribution, double system of point masses) are considered in quasiclassical approximation. Results are used for analysis of meson, baryon resonances of rotating nature, and also for dipion and dinucleon resonances. For oneparticle resonances a string configuration with squared mass distribution is has been chosen. Radius values and their possible changes with spin increase are obtained. At this, in particular, for proton and $δ$-isobar, which are the founders of rotating bands, values 0.45 and 0.63 are defined, respectively. Dipion and dinucleon resonances are pre-sented as two rotating point bodies at distances of some fermy. Each of reso-nances is located in four rotary bands. Possible reasons of formation of some rotary bands for these resonances are discussed.

The comparative analysis of channels of three α-particles and ^12C nuclei production in ^16Op-collisions at 3.25 A GeV/c

New experimental data of the comparative analysis of channels of the production of three α-particles and ^12C nuclei in ^16Op-collisions at 3.25 A GeV/c are submitted. It is shown, that the channel with the three α-particles production is realised in a half part of events as a result of decay of an excited ^12C^* nucleus, and the rest part of the channel - by the knocking-out of one α-cluster from the weakly bound residual nucleus, containing three α-clusters. The modelling of the decay of an excited system on the model of isotropic phase space is justified at small values of excitation energy and, nevertheless, it allows to take the valuable additional information about the dynamics of investigated process from experimental data.
