  The relationship between nuclear temperature and excitation energy of hot
nuclei formed by 8 GeV/c negative pion and antiproton beams incident on 197Au
has been investigated with the ISiS 4-pidetector array at the BNL AGS
accelerator. The double-isotope-ratio technique was used to calculate the
temperature of the hot system. The two thermometers used (p/d-3He/4He) and
(d/t-3He/4He) are in agreement below E*/A ~ 7 MeV when corrected for secondary
decay. Comparison of these caloric curves to those from other experiments shows
some differences that may be attributable to instrumentation and analysis
procedures. The caloric curves from this experiment are also compared with the
predictions from the SMM multifragmentation model.
