Study of relativistic charged particles production in 84Kr36 emulsion interactions ∼1 GeV per nucleon with wounded nucleon model

Abstract

The experimental results on the multiplicity and probability distribution of the emitted charged pions (Nπ) in the interactions of 84Kr36 projectile at around 1GeV per nucleon with nuclear emulsion targets are reported. In this work, we have employed a wounded nucleon model (WNM) to calculate the total number of wounded nucleons (W) and the total number of interactions (ν). The dependence of average multiplicities of produced relativistic charged particles on the calculated wounded nucleons and total interactions are investigated. The obtained results revealed that the average multiplicity of (Nπ) is dependent on the projectile and target mass number. The calculated values of the total number of wounded nucleons and the total numbers of interactions show a strong dependence on the mass of the colliding nuclei. The emission rate of the mean multiplicity of (Ns) and (Nπ) linearly increases with increasing the total number of wounded nucleons and interactions. © 2019 World Scientific Publishing Company.
