• The correlation between neutron-to-proton yield ratio ( R np) and neutron skin thickness ( δ np) in neutron-rich projectile induced reactions is investigated within the framework of the Isospin-Dependent Quantum Molecular Dynamics (IQMD) model. The density distribution of the Droplet model is embedded in the initialization of the neutron and proton densities in the present IQMD model. By adjusting the diffuseness parameter of neutron density in the Droplet model for the projectile, the relationship between the neutron skin thickness and the corresponding R npis obtained. The results show strong linear correlation between R npand δ npfor neutron-rich Ca and Ni isotopes. It is suggested that R npmay be used as an experimental observable to extract δ npfor neutron-rich nuclei, which is very interesting in the study of the nuclear structure of exotic nuclei, the equation of state (EOS) of asymmetric nuclear matter and neutron-rich matter in astrophysics, etc.

    A new probe of neutron skin thickness

        Abstract:The correlation between neutron-to-proton yield ratio (Rnp) and neutron skin thickness (δnp) in neutron-rich projectile induced reactions is investigated within the framework of the Isospin-Dependent Quantum Molecular Dynamics (IQMD) model. The density distribution of the Droplet model is embedded in the initialization of the neutron and proton densities in the present IQMD model. By adjusting the diffuseness parameter of neutron density in the Droplet model for the projectile, the relationship between the neutron skin thickness and the correspondingRnpis obtained. The results show strong linear correlation betweenRnpandδnpfor neutron-rich Ca and Ni isotopes. It is suggested thatRnpmay be used as an experimental observable to extractδnpfor neutron-rich nuclei, which is very interesting in the study of the nuclear structure of exotic nuclei, the equation of state (EOS) of asymmetric nuclear matter and neutron-rich matter in astrophysics, etc.
