The study of light nuclei production in different interactions at 4.2 AGeV/c

Average multiplicity of light nuclei, produced in different interactions at 4.2 AGeV/c is studied as a function of centrality. A change in multiplicity is observed with increase in the mass of projectile. In 12 CC interactions an unexpected increase in the multiplicity is seen in the most central events. These measurements are compared with the predictions of Cascade and Fritiof models, which fail to account for the experimentally observed effects. In case of 12 CC, it is suggested that the inclusion of nuclear coalescence effect can be an explanation for the deviation of experimental measurements from the models’ predictions.
