Inclusive fragment isotope spectra were measured at 15°, 30°, 45°, and 60°for the Ar36 + Ag reaction at 35 MeV/nucleon. The energy spectra of many isotopes of elements from Be to Ne were obtained. A two-parameter thermal model fits the angular distributions of the low-energy fragments. One parameter, source kinetic energy/temperature, is proportional to fragment mass number. The other, total fragment production cross section, after adjustment for binding energy, has a decreasing exponential dependence on mass number.
