“…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.…”

“…35,36 Some important characteristics, such as the compound multiplicity distribution and the correlations between the compound multiplicity and different charged secondaries, produced in totally disintegrated events for the interactions of 16 O and 28 Si nuclei with emulsion heavy target nuclei, have been studied in an earlier publication. 37 Also, Abd-Allah et al 38 the correlations between different multiplicities in 7 Li-Em and 24 Mg-Em collisions at 3A GeV/c and 4.5A GeV/c, respectively. Despite the above mentioned studies on the multiplicity correlations, there is still a lack of experimental investigations in nucleus-nucleus collisions compared with the results of the calculations, performed according to the MCEM.…”

In the present paper, some results on the correlations of the nucleus-nucleus interactions, at high energy, between different particle multiplicities are reported. The correlations between the multiplicities of the different charged particles emitted in the interactions of 22 Ne and 28 Si nuclei with emulsion at (4.1-4.5)A GeV/c have been studied. The correlations of the compound multiplicity nc, defined as the sum of both numbers of the shower particles ns and grey particles ng, have been investigated. The experimental data have been compared with the corresponding theoretical ones, calculated according to the modified cascade evaporation model (MCEM). An agreement has already been fairly obtained between the experimental values and the calculated ones. The dependence of the average compound multiplicity, on the numbers of shower, grey, black and heavy particles is obvious and the values of the slope have been found to be independent of the projectile nucleus. On the other hand, the variation of the average shower, grey, black and heavy particles is found to increase linearly with the compound particles. A strong correlation has been observed between the number of produced shower particles and the number of compound particles. Moreover, the value of the average compound multiplicity is found to increase with the increase of the projectile mass. Finally, an attempt has also been made to study the scaling of the compound multiplicity distribution showing that the compound multiplicity distribution is nearly consistent with the KNO scaling behavior.

Multiplicity distributions of shower particles and target fragments in 84 Kr 36–emulsion interactions at 1 GeV per nucleon

et al. 2013

View full text Add to dashboard Cite

The article focuses on the multiplicity distributions of shower particles and target fragments for the interaction of 84 Kr 36 possessing kinetic energy of ~1 GeV per nucleon with NIKFI BR-2 Nuclear Emulsion target. The experimental multiplicity distributions of shower particles, grey fragments, black fragments, and heavily ionization fragments are well described by the multicomponent Erlang distribution of the multi-source thermal model. We observed a linear correlation in multiplicities for the above mentioned particles or fragments. The further experimental studies showed that with the increase of target fragment multiplicity, a saturation phenomenon was observed in shower particle multiplicity.
