¹⁴N + ¹⁵⁴Sm Collisions

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.
