摘要:

The inclusive light fragment(Z⩽7)yield data inAu+Aureactions, measured by the EOS Collaboration at the LBNL Bevalac, are presented and discussed. For peripheral collisions the measured charge distributions develop progressively according to a power law which can be fitted by a single &tgr; exponent independently of the bombarding energy in the range 250–1200 A MeV. In addition to this universal feature, we observe that the location of the maximum in the individual yields of different charged fragments shift towards lower multiplicity as the fragment charge increases fromZ=3toZ=7.This trend is common to all six measured beam energies. Moments of charge distributions and correlations among different moments are reported. Finally, theTHe,DTthermometer has been constructed for central and peripheral collisions using the double yield ratios ofHeandD,Tprojectile fragments. Themeasurednuclear temperatures are in agreement with experimental findings in other fragmentation reactions. ©2001 American Institute of Physics.
