Nuclear Dynamical Quadrupole Deformations in Heavy-Ion Reactions

Within the quantum molecular dynamics model, the evolution of heavy-ion quadrupole deformations as a function of the central distance between nuclei in the approaching process of fusion reactions near the barrier is studied. The dependences of the maximum prolate deformations for the projectile and the target on the incident energy and the impact parameter are also investigated. The ratios of the quadrupole deformation energies for the projectile to those for the target during the approaching process are also calculated and the results are compared with the assumption [Phys.
