The experimental projected angular distributions of black fragments produced in siliconemulsion collisions at 4.5A GeV/c (the Dubna momentum) are reported in detail. An obvious dependence of the projected angular distribution on polar angle is observed. We introduce the reaction plane flows using the momentum components in the reaction plane. Directed reaction plane flow and elliptic reaction plane flow are observed. ... إقراء المزيد

The spatial, azimuthal, and projected angular distributions of black and gray target fragments produced in magnesium-emulsion collisions at 4.5A GeV/c (the Dubna synchrophasotron momentum) are reported. A multisource ideal gas model is used to describe the experimental angular distributions. The Monte Carlo calculated results are in agreement with the experimental data. إقراء المزيد
