Characteristics of compound multiplicity in 84Kr36 with various light and heavy targets at 1 GeV per nucleon

Abstract

Present article focuses on the interactions of 84 Kr 36 having kinetic energy around 1 GeV per nucleon with NIKFI BR-2 nuclear emulsion detector's targets, that can reveal important features of some compound multiplicity. The observation showed that the width of the compound multiplicity distributions and value of the mean compound multiplicity have linear relation with the mass number of the projectile as well as colliding system.

Study of multiplicity correlations in nucleus–nucleus interactions at high energy

“…Also, it can be observed that the values of the slope in the case of n c and n s , n g correlations are almost of the same order for heavy-ion interactions. Moreover, by comparing the results of the present work with previous reported ones, 27,[47][48][49]50,53,54 it may be observed that the dependence of n c on n b and n h is strong in case of heavy-ion interactions, however, this dependence becomes weak for pion [47][48][49] and proton-nucleus collisions. 50,54 This means that the degree of disintegration of target nuclei depends on the number of compound particles n c (shower n s and grey n g ) produced in the events for heavy interactions or nucleusnucleus interactions, but this dependence is not seen for the case of hadron-emulsion interactions.…”

“…24 Multiplicity distributions for the emitted particles have been found to obey the Koba-Nielsen-Olesen (KNO) type of scaling law. [25][26][27] Multiplicity correlations and KNO scaling in pion-nucleus interactions have been investigated by Tufail et al 28 The properties of the new parameter named compound multiplicity, which is the sum of both relativistic shower and grey particles per interaction, may play an important role in revealing the mechanism of the nucleus-nucleus interaction and in understanding the reaction dynamics in high-energy nuclear interaction. The importance of investigating the grey particles is due to the fact that they are emitted during, or shortly after, the passage of a leading particle.…”

“…Mohery and Arafa 23 have presented some characteristics of the compound multiplicity in high-energy nucleus-nucleus interactions. Recently, the characteristics of the compound multiplicity in 84 Kr with various light and heavy targets at 1 GeV per nucleon have been investigated by Chouhan et al 27 In addition, recently several authors [30][31][32][33][34][35][36][37][38] have investigated some characteristics of the multiplicity correlations. Ghosh et al 30 have studied the rapidity dependence of the multiplicity fluctuations and correlations in high-energy nucleusnucleus interactions.…”

Scaling of multiplicity distribution in high energy hadron-nucleus interactions

“…The values of the parameters obtained by us are A=1.50±0.29, B=-0.007±0.03, C=0.17±0.13 and D=-0.95±0.13 with  2 /dof=0.64. Many workers [13,15,17,20,[26][27][28] have tested the KNO scaling law for AA interactions data as well. In the present investigation, we have made an attempt to study KNO scaling in pion-nucleus interactions at 50 and 340 GeV, and proton-nucleus interactions at 400 GeV for compound multiplicity distribution.…”

Analysis of Various Projectile Interactions with Nuclear Emulsion Detector Nuclei at ~1 GeV per Nucleon Using Coulomb Modified Glauber Model

“…In these regions, heavy-ion collision provides us information to understand the mechanism of nuclear fragmentation, space-time development of hadronic interactions under extreme condition, and formation of exotic nuclei [5][6]. The photographic nuclear emulsion detector is one of the excellent tools to understand the high-energy interactions because it provides excellent spatial resolution and very high efficiency of charge particle detection over complete solid angle [7][8][9][10].…”
