Abstract
The experimental data on the interactions of 10.6A GeV gold nuclei in nucle ar emulsions are analyzed with particular emphasis of target separation int eractions and study of critical exponents. Charged fragment moments, condit ional moments as well as two and three - body asymmetries of the fast movin g projectile particles are determined in terms of the total charge remainin g bound in the multiply charged projectile fragments. Some differences in t he average yields of helium nuclei and heavier fragments are observed, whic h may be attributed to a target effect. However, two and three-body asymmet ries and conditional moments indicate that the breakup mechanism of the pro jectile seems to be independent of target mass. We looked for evidence of c ritical point observable in finite nuclei by study the resulting charged fr agments distributions. We have obtained the values for the critical exponen ts gamma, beta and tau and compare our results with those at lower energy e xperiment (1.0A GeV data). The values suggest that a phase transition like behavior, is observed.
