Description
Nuclear deformation is a key structural property that strongly influences the stability and decay characteristics of neutron-rich nuclei involved in the rapid neutron-capture process (r-process), responsible for the synthesis of heavy elements in astrophysical environments. In this work, we investigate the evolution of quadrupole deformation in exotic nuclei relevant to the r-process path using the self-consistent Hartree–Fock–Bogoliubov (HFB) approach with Skyrme effective interactions.
Quadrupole deformation parameters, binding energies, and two-neutron separation energies are analyzed to explore shape evolution and shell effects in nuclei approaching the neutron drip line. Changes in nuclear shape may affect the location of waiting-point nuclei along the r-process, thereby influencing the final abundance distribution of heavy elements.
The results provide theoretical insights into the role of nuclear deformation in nuclei relevant to r-process nucleosynthesis.
