Magic numbers in exotic nuclei and spin-isospin properties of the NN interaction.
نویسندگان
چکیده
The magic numbers in exotic nuclei are discussed, and their novel origin is shown to be the spin-isospin dependent part of the nucleon-nucleon interaction in nuclei. The importance and robustness of this mechanism is shown in terms of meson exchange, G-matrix, and QCD theories. In neutron-rich exotic nuclei, magic numbers such as N = 8, 20, etc. can disappear, while N = 6, 16, etc. arise, affecting the structure of the lightest exotic nuclei to nucleosynthesis of heavy elements.

Nolen-Schiffer Anomaly in mirror nuclei due to the NN interactions with isospin mixing between T=0 and T=1 mesons of the same spin and parity are investigated. With the computation of coulomb energy along with the charge symmetry breaking (CSB) effects provide a reasonably accurate description of binding energy differences between 39ca- 39k- , 41cs- 41ca mirror nuclei.

Meson is composed of one quark and one antiquark moving under the effect of confinement, oscillating and color potentials. Since quarks are particles with spin , there is a spin-spin interaction potential. Also we have isospins for u and d quarks and we can consider related potentials on isospin-isospin and spin-isospin effects. By comparing the given meson spectrum with the amount calculated...

The isospin dependence of the spin-orbit interaction in light neutron rich nuclei is investigated in the framework of relativistic mean field theory. The magnitude of the spin-orbit potential is considerably reduced in drip line nuclei, resulting in smaller energy split-tings between spin-orbit partners. The effect does not depend on the parametrization of the effective Lagrangian. The results ...
متن کاملMagic numbers in the neutron-rich oxygen isotopes
In this article we report on the theoretical implications for new magic nuclei that have recently been discovered in the neutron-rich oxygen isotopes (Z = 8) out to the neutron drip line at neutron number N = 16. The single-particle shell structure of nuclei provides the bridge for understanding the rich features of these mesoscopic systems in terms of the interactions between nucleons. On one ...

In most models, mesons consist of quark -antiquark pairs moving in a confining potential. However, it would be interesting to consider the effect of an extra residual interaction by introducing the quark particles which contain a dependent spin and isospin. In the Chiral constituent quark model, the hyperfine part of the potential is provided by the interaction of the Goldstone bosons, which ...
