Abstract

The charge-moment technique has been used to study the fragment charge distribution for the $^{3} {H e (4.8 G e V) +}^{197} Au$ reaction. A large variety of fragment charges characterized by a relative variance $\sim 2.3,$ is observed for excitation energies around 5.5 MeV/nucleon. Similar signals related to a phase transition are predicted by the percolation model and the statistical multifragmentation model. Effects of detector acceptance and contribution from fission are discussed.
