核晕结构与赝自旋对称性

Nuclear halo structure and pseudo-spin symmetry

Wen Hui Long, Peter Ring, Jie Meng, Nguyen Van Giai, Carlos A. Bertulani

摘要:

在相对论Hartree-Fock-Bogoliubov(RHFB)理论框架下研究了核晕结构和相对论对称性的恢复。在接近中子滴线的铈同位素中发现了巨大的晕和普通的晕。赝自旋对称性(PSS)的恢复是T=0通道的桥梁,对稳定中子晕结构起着重要作用。Fock项,特别是$ρ$ -张量耦合,不仅在PSS恢复中起重要作用,而且对T=0 {channel}也有重要贡献,这充分证明了Fock项的必要性.

英文摘要:

Nuclear halo structure and restoration of relativistic symmetry are studied within the framework of the relativistic Hartree-Fock-Bogoliubov (RHFB) theory. Giant halos as well as ordinary ones are found in Cerium isotopes close to the neutron drip line. Bridged by T=0 {channel}, the restoration of pseudo-spin symmetry (PSS) plays an essential role in stabilizing the neutron halo structures. The Fock terms, especially the $ρ$-tensor couplings, not only play significant role in the PSS restoration but also present substantial contributions to the T=0 {channel}, from which is well demonstrated the necessity of Fock terms.
