Signals of bimodality have been investigated in experimental data of quasi-projectile decay produced in Au + Au collisions at 35A MeV. This same data set was already shown to provide several signals characteristic of a first order, liquid–gas-like phase transition. Different event sortings proposed in the recent literature are analyzed. A sudden change in the fragmentation pattern is revealed by the distribution of the charge of the largest fragment, compatible with a bimodal behavior.

Abstract
Signals of bimodality have been investigated in experimental data of quasi-projectile decay produced in Au + Au collisions at 35A MeV. This same data set was already shown to provide several signals characteristic of a first order, liquid–gas-like phase transition. Different event sortings proposed in the recent literature are analyzed. A sudden change in the fragmentation pattern is revealed by the distribution of the charge of the largest fragment, compatible with a bimodal behavior.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
