A Giant Halo at the Neutron Drip Line
Relativistic Hartree-Bogoliubov (RHB) theory in coordinate space is used to describe the chain of even-even Zirconium isotopes reaching from Zr to the drip line nucleus Zr. Pairing correlations are taken into account by a density dependent force of zero range. For neutron numbers larger than the magic number N = 82 a giant neutron halo outside the core of Zr is observed. It is formed by up to s...
متن کاملRare isotope production near the neutron drip line
The underlying mechanism involved in the production of very neutron-rich nuclides using projectile fragmentation is studied with an abrasion-ablation ~AA! model. The AA model suggests that very neutron-rich nuclides are produced by removing nearly all the required protons in the nonequilibrium abrasion stage, with minimal evaporation of neutrons in the ablation stage—‘‘cold fragmentation.’’ Fur...
متن کاملThe Pseudo-spin Symmetry in Zr and Sn Isotopes from the Proton Drip Line to the Neutron Drip Line
Based on the Relativistic continuum Hartree-Bogoliubov (RCHB) theory, the pseudo-spin approximation in exotic nuclei is investigated in Zr and Sn isotopes from the proton drip line to the neutron drip line. The quality of the pseudo-spin approximation is shown to be connected with the competition between the centrifugal barrier (CB) and the pseudo-spin orbital potential (PSOP). The PSOP depends...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولShape 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...
