摘要：

Light-particle emission from Au+Au collisions has been studied in the bombarding-energy range 100-250 A . MeV, using Delta E-E(R) telescopes in coincidence with the FOPI detector in its phase I configuration. Center-of-mass energy spectra have been measured for Z = 1, 2 isotopes emitted in central collisions at CM polar angles between 60 degrees and 90 degrees. Evidence for a collective expansion is reported, on the basis of the mean kinetic energies of hydrogen isotopes. Comparison is presented with statistical calculations (WIX code). For CM kinetic energy spectra, fair agreement is found between data and a recently developed transport model.
