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

Abstract

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.

Reaction Cross Section of Heavy Projectiles Using Coulomb Modified Glauber Model

“…The investigation of such interactions provides information regarding geometry of collision in both cases of symmetric and asymmetric collisions [1][2]. Nuclear emulsion detector is a widely used one of the oldest particle detectors for the investigation of the nuclear interactions because of the superb spatial resolution and 4π acceptance [3][4][5]. In heavy ion collision, one of the most important physical quantities is the total reaction cross section, which is useful in the study of nuclear reactions and nuclear models [6].…”

Correlations of Singly and Doubly Charged Projectile Fragments with Secondary Charged Particles Produced in 32S-Emulsion Interactions at 3.7A and 200A GeV

“…In heavy ion collisions, multifragmentation is considered a good tool to understand nuclear structure and fragmentation properties [1][2]. In high energy physics, the nuclear emulsion detector technique plays an important role investigating nucleus-nucleus and nucleus-hadrons collisions, since it has the highest spatial resolution 4π, and excellent detection of relativistic particles.…”
