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

Table 4

The amount of nuclear matter involved in the projectile-emulsion (A-A) interaction for different projectiles with nuclear emulsion target at incident energies ~1 GeV/n is estimated. These calculated values are averaged over the impact parameter.
