“…For Sn isotopes, although PC-PK1 slightly overestimates the neutron skin thickness in comparison with DD-PC1, it nicely reproduces the isotopic trend. For 208 Pb, all the interactions except DD-PC1 give similar neutron skin thicknesses which are larger than the data deduced from antiprotonic atoms [48], polarized proton scattering [49,50], elastic proton scattering [51], proton-nucleus elastic scattering [47], and agree within the experimental error bar with that from inelastic α scattering [52]. The slightly overestimated neutron skin thicknesses are due to the enhanced symmetry energies for nuclear matter shown in Table IV. In overall, the DD-PC1 parametrization provides better description of experimental charge radii and neutron skin thickness due to its smaller symmetry energy at saturation density.…”

A new parametrization PC-PK1 for the nuclear covariant energy density functional with nonlinear point-coupling interaction is proposed by fitting to observables of 60 selected spherical nuclei, including the binding energies, charge radii and empirical pairing gaps. The success of PC-PK1 is illustrated in the description for infinite nuclear matter and finite nuclei including the ground-state and low-lying excited states. Particularly, PC-PK1 provides good description for isospin dependence of binding energy along either the isotopic or the isotonic chains, which makes it reliable for application in exotic nuclei. The predictive power of PC-PK1 is also illustrated for the nuclear low-lying excitation states in a five-dimensional collective Hamiltonian in which the parameters are determined by constrained calculations for triaxial shapes.

“…Several attempts have been made to determine neutron skin thickness. These include hadron scattering [18,19], π − scattering [20], antiprotonic atoms method [21,22], giant dipole resonance (GDR) method [23,24], spindipole resonance (SDR) method [25,26], Gamow-Teller resonance (GTR) method [27] etc. Almost all these methods are strongly model dependent due to the complexity of the strong interaction between nucleons.…”

Triton/3He ratio as an observable for neutron-skin thickness

Based on the framework of the Isospin-Dependent Quantum Molecular Dynamics (IQMD) model in which the initial neutron and proton densities are sampled according to the droplet model, the correlation between triton-to-3 He yield ratio (R(t/ 3 He)=Yield(t)/Yield( 3 He)) and neutron skin thickness (δnp) in neutron-rich projectile induced reactions is investigated. By changing the diffuseness parameter of neutron density distribution in the droplet model for the projectile to obtain different δnp, the relationship between δnp and the corresponding R(t/ 3 He) in semi-peripheral collisions is obtained. The calculated results show that R(t/ 3 He) has a strong linear correlation with δnp for neutron-rich 50 Ca and 68 Ni nuclei. It is suggested that R(t/ 3 He) could be regarded as a good experimental observable to extract δnp for neutron-rich nuclei because the yields of charged particles triton and 3 He can be measured quite precisely.

“…We have analysed the bulk of the existing experimental data (mainly from LAMPF, IUCF and TRIUMF accelerators [8][9][10][11][12]) for elastic proton scattering at several energies: 160, 180, 200, 280, 400, ,489, 500 and 800 MeV, from two target nuclei, namely; 58 Ni and 90 Zr. The experimental data consists of , in all cases, the differential cross section and analysing power measurements at many scattering angles.…”

Elastic proton scattering at energies between 160 and 800 MeV from 58Ni and 90Zr has been studied within the global Dirac optical model. In this work we calculate potential parameters which give good fits to the experimental data using parameterization code comprising differential cross section and analysing power measurements using DWUCK4. The real and imaginary potentials are well determined and behave regularly with energy. The behaviour of the real central effective potential shows the development of a "wine-bottle" shape in the transition energy region and the persistence of a small attractive potential in the nuclear surface region, even at 800 MeV.
