摘要：

We have studied the yield of individual. fragments formed in the projectile fragmentation of gold nuclei at 1 AGeV incident on a carbon target as a function of the total charge multiplicity, The yields of fragments of different nuclear charge peak at different multiplicities, We show that this behavior can be used to determine the critical exponent a. We obtain a =0.68+/-0.05, consistent with the liquid-gas value.
