The charge-moment technique has been used to study the fragment charge distribution for the {sup 3}He(4.8thinspGeV)+{sup 197}Au reaction. A large variety of fragment charges characterized by a relative variance {approximately}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. {copyright} {ital 1998} {ital The American Physical Society}
