Structures and angular distributions of slow and relativistic charged particles produced in 7Li-emulsion interactions at 3 GeV/c per projectile nucleon
Experimental results on the multiplicity distributions of various particles produced in the interactions of 7Li with emulsion nuclei at a momentum of 3 GeV/_c_ per projectile nucleon are reported. A comparison with data on collisions induced by other nuclei at a nearly identical momentum per nucleon is presented in order to reveal the dependence on the projectile mass. The internal ... إقراء المزيد

Features of the Compound Multiplicity of the Interactions of^{24} Mg and^{28} Si Ions with Emulsion Nuclei at 4.5 A GeV/c
The present paper deals with the interactions of^{24} Mg and^{28} Si nuclei at 4.5 A GeV/c with emulsion. Some characteristics of the compound multiplicity given by the numerical sum of grey and shower particles have been investigated. The obtained results indicate that the compound multiplicity distribution is consistent with KNO-Scaling and its width increases with the size of the projectile ... إقراء المزيد

CHARACTERISTICS OF RELATIVISTIC CHARGED PARTICLES PRODUCED IN 24 Mg–EMULSION INTERACTIONS AT 4.5 A GeV/C
The interactions of 4.5A GeV/c 24Mg nuclei with emulsion have been studied. The multiplicity distributions of all the produced target protons from 24Mg–emulsion interactions has been found to obey the KNO scaling behavior. The angular characteristics of the relativistic charged particles have been investigated and their dependence on the multiplicity of the relativistic shower particles has been studied. The results ... إقراء المزيد

Characteristics of the total disintegration of AgBr nuclei by 24Mg and 32S nuclei at 4.5 A GeV/c
The interactions of 4.5 A GeV/_c_24Mg and 32S nuclei with emulsion were studied. The experimental inelastic mean free path for these interactions is compared with theoretically calculated values. The average multiplicities of the emitted secondary charged particles for total disintegration were investigated. Total disintegration events are analysed to investigate the characteristics of secondary charged particles produced in such collisions. The ... إقراء المزيد

Determination of the reaction plane and collective flow in nucleus-nucleus interactions at 4.5 a GeV/c
Nuclear emulsions are used to investigate spallations produced by 4.5 A GeV/c 24 Mg and 28 Si nuclei. The integral multiplicity distribution of disintegrated particles from target nuclei is used to separate the inelastic interactions with the free hydrogen (H), the light (CNO), and the heavy (AgBr) nuclei. Angle of flow, transverse momentum, angular characteristics, and azimuthal alignment data are ... إقراء المزيد

Characteristics of charged projectile fragments from {sup 24} Mg-emulsion interactions at 4.5 A GeV/c
A total sample of 1719 inelastic interactions of {sup 24} Mg in emulsion at 4.5 A GeV/c has been used to study the characteristics of projectile fragments. The multiplicity and angular distributions of projectile fragments in interactions with different target components have been investigated. The projected angular distributions of fragments exhibit features of limiting fragmentation. These distributions are consistent with ... إقراء المزيد
