X. Viñas, M. Centelles, M. Warda

摘要:

利用Skyrme力SkM $^*$,通过半经典扩展的B-Fermi计算,分析了气泡和环面等奇异原子核结构.中子和质子密度的变分方程求解完全自洽球(气泡)和圆柱(环面)对称。讨论了在某些天体物理场景中可能存在的气泡组态。研究了环形结构对四极矩变化的稳定性。能量的全局最小值存在于

英文摘要:

Exotic nuclear structures such as bubbles and tori are analyzed through semiclassical extended Thomas-Fermi calculations with the Skyrme force SkM$^*$. The variational equations for neutron and proton densities are solved fully self-consistently in spherical (bubbles) and cylindrical (tori) symmetries. The possible existence of bubble configurations in some astrophysical scenarios is discussed. The stability of toroidal structures against change of quadrupole moment is studied. A global minimum of the energy is found in heavy
