Abstract

The charge distribution of the intermediate mass fragments produced in p $(8.1 GeV) + Au$ collisions is analyzed in the framework of the statistical multifragmentation model with the critical temperature for the nuclear liquid-gas phase transition $T_{c}$ as a free parameter. It is found that $T_{c} = 20 \pm 3 MeV$ (90% C.L.).
