Characteristics nC- And nTa- Interactions At P=4.2 GeV/s

Full text: The study of multiple production processes of particles in a nucleus-nuclear encounter at high energies has a large meaning for understanding the mechanism of strong interaction in which many nuclei participate. For finding out strong interaction mechanism of hadron-nuclear and the nucleus-nuclear interactions are often used the method of comparing of results received in experiment with forecast of existing theoretical models, as well as in cascade evaporated model (CEM), FRITIOF, quark-gluon model of strings and others. In the present work an average and large number of characteristics of momentum and angular distributed secondary π-mesons, educated nC and nTa interactions at p=4.2 GeV/s are studied. The experimental data given in this work, taken from statistics more greatly than [1] (statistics enlarged more than two times). The comparison of experimental data with QGS Model shows, that the model reproduces well experimental results in particular variety and average meaning kinematics' variable ( π-meson). In the job, the material received on propane with 2-m in the bubble-chamber (LHE JINR), irradiated deuterons in bunches with impulse 4.2 GeV/s on nucleon was used. Neutrons' interaction with a nucleus at target was allocated from interactions of deuterons with nuclei of carbon, proceeding of presence at these events' stripping proton. Stripping was considered particles with momentum p>3 GeV/s and a corner was taken less than 3o. Experimental π - meson's distributions are compared with appropriate distributions obtained from the model of quark-gluons' jets (QGSM). References: 1. Bekmirzaev R.N. et al.
