A wide variety of observables indicate
that maximal fluctuations in the
disassembly of hot nuclei with A ~
36 occur at an excitation energy of
5.6 +
0.5 MeV/u and temperature of 8.3 +
0.5 MeV. Associated with this
point of maximal fluctuations are
a number of quantitative indicators of
apparent critical behavior. The associated
caloric curve does not appear
to show a plateau such as that seen
for heavier systems. This suggests
that, in contrast to similar signals
seen for apparent first order
liquid-gas transitions in heavier
nuclei, the observed behavior in these
very light nuclei is associated with
a transition much closer to the
critical point.
