摘要:

在标准Skyrme有效相互作用中加入D波项的可能性在过去已被广泛考虑。这样的一项已被证明出现在次到次到领先的顺序Skyrme赝势。本文的目的是提供必要的工具,将这一项在一个拟合过程:第一,一个平均场方程写在球对称,以描述球形核和第二,响应函数来检测非物理不稳定性。有了这些工具,将有可能建立一个新的拟合程序,以确定新的功能的耦合常数。

英文摘要:

The possibility of adding a D-wave term to the standard Skyrme effective interaction has been widely considered in the past. Such a term has been shown to appear in the next-to-next-to-leading order of the Skyrme pseudo-potential. The aim of the present article is to provide the necessary tools to incorporate this term in a fitting procedure: first, a mean-field equation written in spherical symmetry in order to describe spherical nuclei and second, the response function to detect unphysical instabilities. With these tools it will be possible to build a new fitting procedure to determine the coupling constants of the new functional.
