摘要

摘要利用魔核（({}^{40,48}\)Ca、({}^{68,78}\)Ni、({}^{132}\)Sn和({}^{208}\)Pb）的例子，研究了电偶极子极化性与中子 "皮肤 "厚度之间的相关性。在随机相近似中，使用 Skyrme 能量密度函数计算了 \(E1\)-转变强度的分布。通过与实验数据的比较，可以在 \(J=30{-}37\) MeV 的范围内限制核对称能的值。

Electric Dipole Polarizability of Magic Nuclei

Using the examples of magic nuclei \({}^{40,48}\)Ca, \({}^{68,78}\)Ni, \({}^{132}\)Sn, and \({}^{208}\)Pb, the correlation between electric dipole polarizability and the thickness of the neutron ‘‘skin’’ has been studied. The distribution of \(E1\)-transition strength was calculated within the random phase approximation using the Skyrme energy density functional. Comparison with experimental data made it possible to constrain the value of nuclear symmetry energy within the range \(J=30{-}37\) MeV.
