Multi-Particle Correlation among Grey particles Emitted in Nucleus-Nucleus Interactions

The short range correlation among the emitted knock on nucleons from heavy ion collisions is used to reveal the dynamic characteristics of the reactions at medium and high energy collisions. Two and three particle correlations are considered in angular space to explain the emission of particles from collectively excited states of the nucleus as a Fermi liquid drop. Positive correlation is detected only among particles emitted in the extreme backward direction which is the coldest domain, and interpreted as direct nonstatistical emission (splashing) of nucleons via the dynamical distortion of the Fermi surface accompanying the collective motion
