The short range correlation among emitted knock on
nucleons from heavy ion collisions is used to reveal the
dynamic characteristics of the reactions at high energy.
Two- and three-particle correlations are
considered in angular space to explain the emission of gray
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. It is interpreted as direct
non-statistical emission (splashing) of nucleons via the
dynamical distortion of the Fermi surface accompanying
the collective motion.
