INVESTIGATION OF COLLECTIVE STREAMS IN Au+Au-INTERACTIONS OF INTERMEDIATE ENERGIES

Abstract

The method for investigation of the collective streams, which doesn't require the restoration of the reaction plane and is free upon the non-prevented errors connected with experimental determination of the reaction plane has been developed. On base of the developed method a number of the principial-new results characterizing the directed stream (for example, equality of directed stream speeds among fragments with Z=2, 3; the lesser value of directed steam speed among fragments with Z=1, increase and them decrease of directed stream speed with interaction centrality growth), non-directed stream (the energy of the directed cross stream is equal for fragments with Z=1, 2, 3) has been obtained, and a number of the earlier-observed effects has been confirmed. The results can be used both in the experimental and in the theoretical investigations of the collective streams in the interaction of the nuclei of the sufficient wide range of the energies (E/A=50-500 MeV)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
