Abstract
The fragmentation resulting from peripheral Au + Au collisions at an incident energy of E = 35 MeV/nucleon is investigated. A power-law charge distribution, A-τ with τ≈ 2.2, and an intermittency signal are observed for events selected in the region of the Campi scatter plot where "critical" behavior is expected.
