TEMPERATURE-MEASUREMENTS FOR CENTRAL AU-MEV(AU COLLISIONS AT 35A)

The breakup temperatures for central Au + Au collisions at 35A MeV hav e been determined from the relative populations of excited states of L i-5, He-4, and B-10 fragments and nine double ratios involving the yie lds of elements with 1 less than or equal to Z less than or equal to 6 . Unlike results reported at significantly higher energies, all thermo meters yield temperatures that an consistent within the experimental u ncertainties. Extrapolation of thr data to zero impact parameter yield s T-cm = 4.6 +/- 0.4 MeV, somewhat lower than the temperature assumed in statistical multifragmentation model calculations which describe mo st of the other features of this reaction.
