Abstract

We analyse the multifractal structure of moments Gq in terms of a new variable X on data of 197Au, 32S and 16O induced interactions with emulsion nuclei and Monte Carlo generated samples. The dynamical properties of the produced particles are mapped onto multifractal spectra. We compare ln G in experimental data of 197Au, 32S and 16O with pure statistical fluctuations. It is shown that the stochasticity plays an important role for the G-moments.

Abstract

Contribution of the unstable nuclei 7Be, 8Be and ®B into coherent dissociation events ("white" stars) of relativistic nuclei 7,9Be, 10B and 10,11C is under study on the basis of a nuclear track emulsion exposed to beams of the JINR Nuclotron. Distributions over the opening angle of α-pairs indicate to a simultaneous presence of virtual 8Beg.s. and 8Be2+ states in the ground states of the 9Be and 10C nuclei. The core 9B is manifested in the 10C nucleus with a probability of (30 ± 4)%, Selection of the 10C "white" stars accompanied by 8Beg.s. (9B) leads to the appearance in the excitation energy distribution of 2α2p "quartets" of the distinct peak with a maximum at 4.1 ± 0.3 MeV. 8Beg.s. decays are presented in 21% 2He + 2H and 19% in the 3He of the all 11C "white" stars. 9Bg.s. decays are identified in "white" stars 11C → 2He + 2H constituting 14% of the 11C "white" stars. The 9B nucleus. is manifested in the "white" stars 10B → 2He + 2H with a probability of (9 ± 1)%. For the 10B case yield of 8Beg.s. nuclei with the respect to 9B is about a factor of 3 higher than 9B.

Abstract

Charge distributions of projectile fragments produced in the interactions of 22Ne beams with emulsion at 4.1A GeV/c have been studied. Correlations between projectile and target fragments and among projectile fragments are presented. The change of charge yield distribution with the violence of the collision has been shown. The present analysis contradicts theoretical calculations describing the inclusive charge yield distribution of fragments by a single process.
