Proton-rich Nuclei at and beyond the Proton Drip Line in the Relativistic Mean Field Theory
Ground state properties of proton-rich odd-Z nuclei in the region 55 ≤ Z ≤ 73 are studied in the relativistic mean field (RMF) theory. The RMF equations are solved by using the expansion method in the Harmonic-Oscillator basis. In the particle-particle channel, we use the state-dependent BCS method with a zero-range δ-force, which has been proved to be effective even for neutron-rich nuclei. Al...
متن کاملDiproton decay of nuclei on the proton drip line.
The process of direct two-proton decay of nuclei with Z 22-28 on the proton drip line is considered. On the basis of new Od3t2 Offi2 -shell-model mass extrapolations, '9Ti, 42Cr, 45Fe, Ni, and Ni are found to be bound to single-proton decay but unbound to two-proton decay. New estimates of the spectroscopic factors and lifetimes have been made. The decays of Ti, Fe, and Ni are found to be promi...
متن کاملProton drip-line nuclei in Relativistic Hartree-Bogoliubov theory
Ground-state properties of spherical even-even nuclei 14 ≤ Z ≤ 28 and N = 18, 20, 22 are described in the framework of Relativistic Hartree Bogoliubov (RHB) theory. The model uses the NL3 effective interaction in the mean-field Lagrangian, and describes pairing correlations by the pairing part of the finite range Gogny interaction D1S. Binding energies, two-proton separation energies, and proto...
متن کاملRelativistic mean - field study of light nuclei near drip line
The relativistic mean field theory is applied to study some exotic properties of neutron rich nuclei as recently observed, namely, extension of the drip-line for F nuclei from 29 F to 31 F and the appearence of a new shell closure at neutron number N = 16. We find 31 F to be bound against one-neutron dripping but unbound only marginally for two neutron separation. The calculated functional depe...
متن کاملShape and shell-structure of nuclei towards neutron drip line
In nuclei along the β stability line the nucleons are bound at least by 7–10MeV, and the magic numbers in those nuclei are well known as N (or Z) = 8, 20, 28, 50, 82, and 126. In contrast, in nuclei away from the β stability line the presence of nucleons with binding energy much smaller than 8MeV leads to a unique shell-structure. Consequently, magic numbers may be changed and the nuclei, which...
