Genuine two particle correlations of target fragments in nuclear interactions

The search for genuine two-particle dynamical correlations among the target evaporated slow particles in ¹²CAgBr and ²⁴Mg-AgBr interactions at 4.5 AGeV and ²⁸Si-AgBr interactions at 14.5 AGeV in the emission angle space has been carried out using the method of normalized factorial cumulant moments. The analysis reveals the presence of genuine two-particle dynamical correlations among the target fragments in ¹²C-AgBr, ²⁴Mg-AgBr, and ²⁸Si-AgBr interactions. The correlations among the target evaporated slow particles are found to decrease with an increase in mass and energy of the projectile beam. (author)
