Density functional theory studies of cluster states in nuclei

The framework of nuclear energy density functionals is applied to a study of the formation and evolution of cluster states in nuclei. The relativistic functional DD-ME2 is used in triaxial and reflection-asymmetric relativistic Hartree-Bogoliubov calculations of relatively light N = Z and neutron-rich nuclei. The role of deformation and degeneracy of single-nucleon states in the formation of clusters is analyzed, and interesting cluster structures are predicted in excited configurations of Be, C, O, Ne, Mg, Si, S, Ar and Ca N = Z nuclei. Cluster phenomena in neutron-rich nuclei are discussed, and it is shown that in neutron-rich Be and C nuclei cluster states occur that are characterized by molecular bonding of α-particles by the excess neutrons.

“…spectra, we see that a value of M * s /M close to 1.0 is favored by the 208 Pb data, while 16 O favors a value of 0.8. The 132 Sn data are ambiguous, the neutron spectrum indicating the higher value of M * s /M , and the proton spectrum the lower value.…”

“…In Tables IV -IX and Figure 5 we show the s.p. spectra of 208 Pb, 132 Sn, and 16 O for forces BSk2, BSk3, and BSk6, along with those of the old forces MSk5, MSk5 * and SLy4. Comparing BSk2 and BSk3 shows that making the pairing density-dependent has little effect on the s.p.…”

Asymmetry dependence of nucleon correlations in spherical nuclei extracted from a dispersive-optical-model analysis

et al. 2011

Neutron elastic-scattering angular distributions were measured at beam energies of 11.9 and 16.9 MeV on 40,48 Ca targets. These data plus other elastic-scattering measurements, total and reaction cross sections measurements, (e, e ′ p) data, and single-particle energies for magic and doubly magic nuclei have been analyzed in the dispersive optical model (DOM) generating nucleon self-energies (optical-model potentials) which can be related, via the many-body Dyson equation, to spectroscopioc factors and occupation probabilities. It is found that for stable nuclei with N ≥ Z, the imaginary surface potential for protons exhibits a strong dependence on the neutron-proton asymmetry. This result leads to a more modest dependence of the spectroscopic factors on asymmetry. The measured data and the DOM analysis of all considered nuclei clearly demonstrates that the neutron imaginary surface potential displays very little dependence on the neutron-proton asymmetry for nuclei near stability (N ≥ Z).
