Abstract

Inclusive fragment cross sections and cross sections of coincident γ-ray transitions from the decay of 8Li, 7Be, 10B, 12B and 13C fragments were measured for 32S induced reactions on Ag at 715 MeV. These measurements are compared to quantum statistical model calculations which include sequential feeding from particle unbounds states of heavier fragments. When the uncertainties in the sequential feeding calculations are taken into account, although the measured γ-ray fractions are consistent with temperature, T ⪖ 4 MeV; the calculations demonstrate that the investigated γ-ray transitions cannot be used to determine the temperature of highly excited systems.
