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

Abstract EN

The total nuclear reaction cross section is calculated considering the cases with and without medium effect by employing Coulomb modified Glauber model (CMGM) for interactions of projectiles 56Fe26, 84Kr36, 132Xe54, 197Au79, and 238U92 with nuclear emulsion detector (NED) nuclei at around 1 GeV per nucleon incident kinetic energy.

These calculated nuclear reaction cross sections are correlated with the different target groups of the NED nuclei.

The average value of various parameters is also calculated and compared with the corresponding experimental results.

The number of shower particles emitted in an interaction is also calculated and showed good agreement with the experimental result.

We observed that the total nuclear reaction cross section increases with increasing the target mass number in case of all the considered projectiles.

In addition, it is shown that the average value of reaction cross section with nuclear medium effect is in good agreement with the experimental results for projectiles 56Fe, 84Kr, and 132Xe, although results of projectiles 197Au and 238U are not in agreement with the experimental observations.

This study sheds some light on the energy dependence of the nuclear reaction cross section.
