The impact parameter and energy dependence of the
sign of the mean
transverse momentum of nonequilibrium light charged
particles was
determined from the circular polarization of coincident
g-rays emitted
from residual nuclei for 14N-induced
reactions on 154Sm at incident
energies, E/A=35, 100 and 155
MeV. Results from the emitted alpha
particles from mid-central collisions
show the predicted transition
from mean-field dominated dynamics
at low energies to nucleon-nucleon
collision dominated dynamics
at high energies.
