Investigating the neutron stability of neutron-rich O,Ar, Kr,and Rn isotopes

Properties of extremely neutron-rich even-even O, Ar, Kr, and Rn isotopes in the ground state are calculated by the Hartree-Fock method using Skyrme forces with allowance for axial deformation of the density distribution. It is shown that beyond the familiar two-neutron drip line there can be regions (islands) of nuclei stable with respect to the emission of one or two neutrons. The stability recovery mechanism is described in consideration of the deformation effect. Certain isotopes are compared to calculations performed by the Hartree-Fock-Bogolyubov method, and ^40,42O is compared to calculations performed within the relativistic Hartree-Bogolyubov theory.

Analysis of elastic proton-nucleus scattering on the basis of the Glauber-Sitenko approach with allowance for intermediate excitations of nuclei

On the basis of the Glauber-Sitenko approach, the cross sections and spin observables for proton-nucleus scattering at intermediate energies are calculated with allowance for intermediate excitations of target nuclei. The calculations are performed by using the Hartree-Fock and model-independent nuclear densities and nucleon-nucleon amplitudes determined from partial-wave analyses. It is shown that the inclusion of intermediate excitations of nuclei strongly affects the behavior of observables in the region of moderately small scattering angles.     

Neutron Drip Line for Nuclei in the Vicinity of the Neutron Magic Number N = 184

Ground-state properties of even-even nuclei were calculated over a broad region of mass numbers, including nuclei that contain a neutron excess in the vicinity of the neutron drip line. The calculation of the properties of such nuclei relied on the method of the relativistic and the nonrelativistic mean field and took into account the axial deformation of nuclei. Particular attention was given to nuclei beyond the theoretical neutron drip line, which form a peninsula of nuclei in the (N, Z) space at N = 184 that are stable against the emission of one or two neutrons.
