Initial fluctuations and correlation of finite distributions of secondary particles in interaction of heavy ions with photoemulsion nuclei

The study of the peculiarities of the distribution of secondary particles depending on the degree centrality and the degree of asymmetry of the interacting nuclei, is performed. The number of multicharged fragments of the projectile nucleus $N_f$ in interactions sharply asymmetric nuclei depends on the centrality degree of interaction. At that, the events with $N_f$ =1 are separated clearly in the distribution of the total charge of the fragments of a projectile nucleus $Q$ depending on the nature of the correlation of the number of fragments of the target nucleus and the multiplicity of secondary particles.

Feasibility of the correlation curves method in calorimeters of different types

The simulation of the development of cascade processes in calorimeters of different types for the implementation of energy measurement by correlation curves method, is carried out. Heterogeneous calorimeter has a significant transient effects, associated with the difference of the critical energy in the absorber and the detector. The best option is a mixed calorimeter, which has a target block, leading to the rapid development of the cascade, and homogeneous measuring unit. Uncertainties of energy reconstruction by presented mixed calorimeter on the base of the correlation curves methodology, is less than 10 percent.
