N2 - Fragment production has been studied as a function of the source mass and excitation energy in peripheral collisions of 35Cl+197Au at 43 MeV/nucleon and 70Ge+natTi at 35 MeV/nucleon. The results are compared to the Au+Au data at 600 MeV/nucleon obtained by the ALADIN Collaboration. A mass scaling, by 4source∼ 35 to 190, strongly correlated to excitation energy per nucleon, is presented, suggesting a thermal fragment production mechanism. Comparisons to a standard sequential decay model and the lattice-gas model are made. Fragment emission from a hot, rotating source is unable to reproduce the experimental source size scaling.
