Тhe complete destruction of the Ag, Br nuclei under action of alfa-particles with 1.4 GeV / A. energy are investigated in the emulsion. Measured the angles of s-, g- and b- secondary charged particles in 4π-geometry. The probability of the complete destruction of the Ag, Br nuclei obtained by us, are comparison with the probability of a complete destruction same nuclei by the primary protons and light nuclei at other energies obtained also by using an emulsion technique. The mechanism of formation of g-particles, as well as the possibility of manifestation of collective effects like of shock waves in interaction of fast hadrons and light nuclei with nuclei are discussed. |
