There are experimental evidence of PNKL ( particles near kinematics limit) from nuclear heavy ion interaction. Energy spectra of these particles measured for forward angles cover all the energies up to maximum energy permitted in balance of energy. In the violent collision of the two pieces of nuclear matter, a light particle is outgoing with all initial energy. This accumulated energy suggests a new kind of interaction, cumulative one. We try to find out the properties of this three bodies interaction which act to transform the disordered nuclear matter in an ordered one. The nuclear fusion, the disintegration of the nuclei by alpha decay or through the fission can be understood when this duality of ordered/disordered (O/D) in nuclear matter is considered. This coexistence (O/D) appears clearly for example in the case of shape coexistence for the nuclei in gold region. Roughly estimation of intensity of this cumulative interaction suggests a value between the gravitational and weak interaction intensities. This interaction is responsible for nuclear matter appearance.
