  We study signatures of critical behavior in microscopic simulations of small,
highly excited Lennard-Jones drops. We focus our attention on the behavior of
the system at the time of fragment formation (which takes place in phase space)
and compare the results with the corresponding ones obtained at asymptotic
times (experimentally accessible). The four critical exponents ($\tau$,$\beta$,
$\sigma$ and $\gamma$) found at fragmentation time have shown to be stable
against time evolution, indicating that the asymptotic stage reflects
accurately the physics at fragmentation time. Even though evidence of critical
behavior arises from the calculations, we can not affirm that the system is
performing a second order like phase transition.
