| Abstract: |
Proton-proton correlations and correlations of p-alpha, d-alpha, and
t-alpha from spectator decays following 197Au +
197Au collisions at 1000 AMeV have been measured with
an highly efficient detector hodoscope. The constructed correlation
functions indicate a moderate expansion and low breakup densities
similar to assumptions made in statistical multifragmentation models.
In agreement with a volume breakup rather short time scales were
deduced employing directional cuts in proton-proton correlations.
