原子核中新的有效相互作用、新对称性及奇特核态(英文)

New Effective Interactions, New Symmetry and New States in Atomic Nuclei

总结了近年来对奇特核和极端条件下核物质的研究结果 ,包括原子核的新有效相互作用、新对称性及奇特性质 .在相对论平均场理论中 ,发现了反核子谱中的自旋对称性 ,提出了包含微观质心修正的新相互作用PK1,PK1r和PKDD .这些新相互作用不但可以很好地描述核物质与中子星 ,还可以很好地给出靠近或远离 β稳定线的原子核性质 ,包括中子滴线核与超核中的晕和巨晕现象 .

Recent works on the relativistic description of exotic nuclei and nuclear matter at extreme conditions are reviewed. New effective interactions, PK1, PK1r and PKDD in the relativistic mean field(RMF)theory, are proposed with the center-of-mass correction included in a microscopic way. They are able to provide an excellent description not only for the properties of nuclear matter and neutron stars, but also for the nuclei near or far from the beta-stability line, including halos and giant halos at the neutron drip line in nuclei and hyper-nuclei. Based on the solution of the RMF equations, good spin symmetry is found in anti-nucleon spectra.
