Nuclear temperature measurements and feeding from particle unbound states

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 {slanted equal to or greater-than} 4 MeV; the calculations demonstrate that the investigated γ-ray transitions cannot be used to determine the temperature of highly excited systems.
