The fragmentation resulting from peripheral $\mathrm{Au}+\mathrm{Au}$ collisions at an incident energy of $E=35\mathrm{}\mathrm{MeV}/\mathrm{nucleon}$ is investigated. A power-law charge distribution, $A^{-\tau }$ with $\tau \approx 2.2$, and an intermittency signal are observed for events selected in the region of the Campi scatter plot where “critical” behavior is expected.
