Setting bounds on critical exponents with event-by-event analysis of nuclear fragmentation data Conference Paper

abstract

• An analysis of recent ISiS data [1] is performed and a comparison with percolation-based theories is conducted. We pay particular attention to detector acceptance corrections as well as the role of sequential decays of excited pre-fragments. The corrected data are subjected to a scaling analysis. We find evidence for a continuous phase transition in these nuclear multi-fragmentation events and extract the value for the critical exponents: = 0.5 0.1 and = 2.35 0.05. In addition, we find Tc = 8.3 0.2 MeV.
