Body Correlation

The relativistic density-dependent Hartree framework, where the relativistic two-body correlations are properly incorporated, is developed to study the properties of halo nuclei. The halo nucleon–meson vertex is reconstructed considering the nuclear potentials can be built dominantly from the two-body interactions. The two-neutron halo nucleus 11 Li , together with the one-neutron halo nucleus 19 C , is investigated. Separation energies, root-mean-square (rms) radii, and halo tails of above halo nuclei are nicely reproduced. The correlation contribution which provides essential attractions for halo neutrons is important to guarantee the relation Sn>S2n for 11 Li .

A candidate of a neutron-halo nucleus, 31 Ne , contains a single neutron in the pf shell. Within Glauber and eikonal models, we analyze reactions used to study 31 Ne . We show in a 30 Ne + n model that the magnitudes of the total reaction and above all of the one-neutron removal cross sections of 31 Ne on 12 C and 208 Pb targets strongly depend on the orbital angular momentum of the valence neutron, thereby providing efficient ways to determine the structure of 31 Ne ground state. We also show that elastic-breakup observables exhibit a strong dependence upon the orbital of the valence neutron.

Recently, the energy spectrum of \boldsymbol{^{10}}10Li was measured upto \boldsymbol{4.6}4.6 MeV, via one-neutron transfer reaction \boldsymbol{d(^{9}\textrm{Li},~p)^{10}\textrm{Li}}𝐝(9Li,𝐩)10Li. Considering the ambiguities on the \boldsymbol{^{10}}10Li continuum spectrum with reference to new data, we report the configuration mixing in the ground state of the two-neutron halo nucleus \boldsymbol{^{11}}11Li for two different choices of the \boldsymbol{^{9}{\textrm{Li}}+n}9Li+𝐧 potential. For the present study, we employ a three-body (\boldsymbol{\textrm{core}+n+n}core+𝐧+𝐧) structure model developed for describing the two-neutron halo system by explicit coupling of unbound continuum states of the subsystem (\boldsymbol{\textrm{core}+n}core+𝐧), and discuss the two-neutron correlations in the ground state of \boldsymbol{^{11}}11Li.

Nuclear Photoemulsions

To investigate the structure of two-neutron halo we propose an experimental method of studying neutron-neutron correlations by measuring reactions induced by halo projectile in nuclear photoemulsions. The obtained preliminary data on interaction of halo nucleus 6 He with hydrogen are compared with results of simple kinematical calculations for the reaction of quasi-free scattering of proton by the clusters existing in halo nucleus 6 He .
