Emission of helium nuclei in relativistic proton interactions leading to total break-up of Ag and Br nuclei

Abstract

In this paper the probability of total break up of Ag and Br emulsion nuclei under the bombardment with different relativistic hadrons and heavy nuclei is discussed. The differential energy spectra and angular distribution of the He-nuclei (up to 120 Mev) in inelastic interactions of 69 Gev/C protons leading to both low and high degree of disintegration of Ag and Br nuclei are investigated on the basis of the conventional evaporation and direct mechanisms.

Pseudorapidity distribution of shower particles in relativistic nucleus–nucleus collisions

“…as 22 Ne [21], 24 Mg [22], and 28 Si [27]. The results from our experiment along with those from all other experiments [21,22,27,34,35] at 4.5A GeV/c per nucleon are presented in Fig. 3 where < n s > is plotted as a function of the available center-of-mass energy E. From Fig.…”

“…Figure 4 shows the pseudorapidity distribution in 24 Mg with emulsion at 4.5A GeV/c; it also contains a separate distribution of shower particles from events with n h ≤ 1 (H), 2 ≤ n h ≤ 8 (CNO), n h > 9 (AgBr), and the total sample. Many models have been introduced to describe the multiparticle production in nucleus-nucleus interactions [34][35][36]. One of these models is the Modified Fritiof Model (MFM), which is another Monte Carlo simulation program for inelastic h-N (hadron-nucleon), h-A (hadron-nucleus), and A-A (nucleus-nucleus) interactions.…”
