Ground state properties of neutron rich even-even Be and C nuclei have been investigated using Relativistic Mean Field approach in co-ordinate space. The positions of the neutron drip line are correctly predicted for both the elements. The nucleus Be shows a two neutron halo but, contrary to expectation, C does not exhibit any halo structure. In carbon nuclei, N=16 comes out as a new magic numb...
Reactions with radioactive beams have attracted great experimental and theoretical interest during the last two decades [ 1]. Progresses of this scientific endeavor were reported on measurements of nuclear sizes [ 2], use of secondary radioactive beams to elucidate reactions of astrophysical interest [ 3, 4], fusion reactions with neutron-rich nuclei [ 5, 6], tests of fundamental interactions [...
A new Nilsson single-particle structure is proposed for neutron-rich nuclei near 132Sn. In general, a large reduction in spin–orbit interaction is required and the neutron N = 82 gap persists in the new set of parameters. The ground state deformations for several isotopic chains are studied with this set and compared with the results of the standard set and with measured ones. Collective bands ...
Our recent investigations represent an attempt to the self-consistent description of exotic phenomena in neutron–rich A∼100 nuclei [1, 2] within the complex Excited Vampir variational model with symmetry projection before variation using a realistic effective interaction in a large model space. The triple shape coexistence and the shape evolution in the N=58 Sr and Zr isotopes, the shape evolut...
One-proton and two-proton separation energies are calculated for proton-rich nuclei in the region A = 41 − 75. The method is based on Skyrme Hartree-Fock calculations of Coulomb displacement energies of mirror nuclei in combination with the experimental masses of the neutron-rich nuclei. The implications for the proton drip line and the astrophysical rp-process are discussed. This is done withi...
The new Atomki-V2 ?-nucleus potential is applied to calculate astrophysical reaction rates NA??v? of intermediate mass and heavy target nuclei from iron (Z=26) up bismuth (Z=83). Overall, ?-induced reactions are provided for 4359 nuclei, covering as well neutron-deficient extremely neutron-rich the proton neutron dripline. Contrary previous rate compilations, these calculations include all rele...
The region of neutron-rich nuclei beyond 208Pb has been very difficult to explore due to its high mass and exoticity. However, recent experimental improvements allowed one to perform a quite extended isomer decay spectroscopy of these nuclei.
