Query: Short timescale behavior of colliding heavy nuclei at intermediate
  energies   An Antisymmetrized Molecular Dynamics model is used to explore the collision
of $^{114}$Cd projectiles with $^{92}$Mo target nuclei at E/A=50 MeV over a
broad range in impact parameter. The atomic number (Z), velocity, and emission
pattern of the reaction products are examined as a function of the impact
parameter and the cluster recognition time. The non-central collisions are
found to be essentially binary in character resulting in the formation of an
excited projectile-like fragment (PLF$^*$) and target-like fragment (TLF$^*$).
The decay of these fragments occurs on a short timescale, 100$\le$t$\le$300
fm/c. The average excitation energy deduced for the PLF$^*$ and TLF$^*$
`saturates for mid-central collisions, 3.5$\le$b$\le$6 fm, with its magnitude
depending on the cluster recognition time. For short cluster recognition times
(t=150 fm/c), an average excitation energy as high as $\approx$6 MeV is
predicted. Short timescale emission leads to a loss of initial correlations and
results in features such as an anisotropic emission pattern of both IMFs and
alpha particles emitted from the PLF$^*$ and TLF$^*$ in peripheral collisions.
