Title: Orientation dependence of the heavy-ion potential between two deformed nuclei

Abstract

The deformation and orientation dependence of the real part of the interaction potential is studied for two heavy deformed nuclei using the Hamiltonian energy density approach derived from the well-known Skyrme NN interaction with two parameter sets SIII and SkM*. We studied the real part of the heavy ion (HI) potential for {sup 238}U+{sup 238}U pair considering quadrupole and hexadecapole deformations in both nuclei and taking into consideration all the possible orientations, coplanar and noncoplanar, of the two interacting nuclei. We found strong orientation dependence for the physically significant region of the HI potential. The orientation dependence increases with adding the hexadecapole deformation. The azimuthal angle dependence is found to be strong for some orientations. This shows that taking the two system axes in one plane produces a large error in calculating the physical quantities.

  • In the current study, a simulation technique has been employed to calculate the total potential between two deformed nuclei. It has been shown that this simulation technique is an efficient one for calculating the total potential for all possible orientations between the symmetry axes of the interacting nuclei using the realistic nuclear matter density and the M3Y nucleon-nucleon effective forces. The analysis of the results obtained for the {sup 48}Ca+{sup 238}U, {sup 46}Ti+{sup 46}Ti, and {sup 27}Al+{sup 70}Ge reactions reveal that considering the density dependent effects in the M3Y forces causes the nuclear potential to drop by an amount ofmore » 0.4 MeV.« less
  • The reaction dynamics of axisymmetric deformed {sup 24}Mg+{sup 24}Mg collisions has been investigated systematically by an isospin-dependent quantum molecular dynamics model. It is found that different deformations and orientations result in apparently different properties of reaction dynamics. We reveal that some observables such as nuclear stopping power (R), multiplicity of fragments, and elliptic flow are very sensitive to the initial deformations and orientations. There exists an eccentricity scaling of elliptic flow in central body-body collisions with different deformations. In addition, the tip-tip and body-body configurations turn out to be two extreme cases in central reaction dynamical process.
  • In heavy-ion fusion reactions involving a well-deformed nucleus, one often assumes that the orientation of the target nucleus does not change during the reaction. We discuss the accuracy of this procedure by analyzing the excitation function of the fusion cross section and the fusion barrier distribution in the reactions of {sup 154}Sm target with various projectiles ranging from {sup 12}C to {sup 40}Ar. It is shown that the approximation gradually loses its accuracy with increasing charge product of the projectile and target nuclei because of the effects of finite excitation energy of the target nucleus. The relevance of such inaccuracymore » in analyzing the experimental data is also discussed.« less
  • The azimuthal angle ({phi}) variation of the Coulomb and nuclear heavy ion (HI) potentials is studied in the framework of the double folding model, which is derived from realistic nuclear density distributions and a nucleon-nucleon (NN) interaction. The present calculation shows that the variation of HI potentials with the azimuthal angle depends strongly on the range of the NN forces. For the long-range Coulomb force, the maximum variation with {phi} is about 0.9%, and for HI potential derived from zero-range NN interaction the {phi}-variation can reach up to 90.0%. Our calculations are compared with the recent {phi}-dependence of the HImore » potential derived from proximity method. The present realistic {phi}-dependence calculations of the HI potential is completely different from the results of the proximity calculations.« less
  • The azimuthal angle ({phi}) dependence of the Coulomb barrier parameters (height V{sub b} and position R{sub b}) are studied in the framework of the double-folding model with the realistic M3Y nucleon-nucleon interaction. Different pairs of axially symmetric, deformed nuclei are considered. For the interaction between medium and heavy nuclei, the maximum percentage of {phi} dependence is studied as a function of relative orientations of the interacting nuclei. It appreciably increases as the values of the deformation parameters increase and is sensitive to the hexadecapole deformation. The smallest {phi} variation is found for the relative orientations {theta}{sub P}={theta}{sub T}=90 deg. Themore » {phi} variation of the Coulomb barrier parameters, as calculated in the present paper, is completely different in both magnitude and behavior from those deduced in the widely used proximity approach.« less
