摘要:

在随机相位近似下,采用Skyrme型相互作用作为有效相互作用,研究了中子星内壳的线性响应。我们采用维格纳-塞茨近似,并考虑一个单一的库仑晶格构成的内地壳,在其中心的核,周围的自由中子的海洋单位电池。通过使用适当的算子,可以详细分析原子核表面振动的性质及其与自由中子海模式的相互作用,并研究壳效应和共振态的作用。

英文摘要:

We study the linear response of the inner crust of neutron stars within the Random Phase Approximation, employing a Skyrme-type interaction as effective interaction. We adopt the Wigner-Seitz approximation, and consider a single unit cell of the Coulomb lattice which constitutes the inner crust, with a nucleus at its center, surrounded by a sea of free neutrons. With the use of an appropriate operator, it is possible to analyze in detail the properties of the vibrations of the surface of the nucleus and their interaction with the modes of the sea of free neutrons, and to investigate the role of shell effects and of resonant states.
