Phys. Rev. Lett. 73, 1590–1593 (1994)Determination of Critical Exponents from the Multifragmentation of Gold NucleiReceived 20 May 1994; published in the issue dated 19 September 1994 Using reverse kinematics, we have studied the breakup of 1.0A GeV gold nuclei incident on a carbon target. The detector system permitted exclusive event reconstruction of nearly all charged reaction products. The moments of the resulting charged fragment distribution provide strong evidence that nuclear matter possesses a critical point observable in finite nuclei. We have determined values for the critical exponents γ, β, and τ. These values are close to those for liquid-gas systems and clearly different than those for 3D percolation and the liquid-gas mean field limit. © 1994 The American Physical Society URL:
