摘要:

由Skyrme能量泛函导出了非自旋相关的Landau-Migdal参数的大小和密度依赖关系,并与唯象的结果进行了比较。我们进行RPA计算与各种近似的朗道Migdal粒子-空穴相互作用,并将它们与完整的Skyrme相互作用所获得的结果进行比较。在原子核结构的计算中,首次考虑了Landau-Migdal方法中的次主导级。

英文摘要:

The magnitude and density-dependence of the non-spin dependent Landau-Migdal parameters are derived from Skyrme energy functionals and compared with the phenomenological ones. We perform RPA calculations with various approximations for the Landau-Migdal particle-hole interaction and compare them with the results obtained with the full Skyrme interaction. For the first time the next to leading order in the Landau-Migdal approach is considered in nuclear structure calculations.
