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. C
enter-of-mass energy spectra have been measured for Z = 1, 2 isotopes
emitted in central collisions at CM polar angles between 60 degrees an
d 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 en
ergy spectra, fair agreement is found between data and a recently deve
loped transport model.
