A study of characteristics of the events of complete destruction of the projectile nucleus in the interactions between asymmetric nuclei for different initial states of the collision is performed. In the interactions of the sulfur nuclei with heavy emulsion nuclei at energy of 200 AGeV, an anomalous high number of events of complete destruction of the projectile nuclei is observed. The high probability of such events depends on the energy of interaction (it is not detected in the interactions of the sulfur nuclei with emulsion nuclei at the energy of 3.7 AGeV) on the degree of asymmetry of the interacting nuclei (it is not detected in interactions of the sulfur nuclei with light emulsion nuclei) and on the initial state of interaction (it is not detected in peripheral collisions). These events are characterized by high multiplicity of secondary particles and a narrow peak in the region of small values of average pseudorapidity.
