论文摘要
我们提出了新的Gogny型有限范围有效互动，包括中央学期的第三高斯。基于对任意径向形式有效的简单参数，这三个范围是从物理基础固定的，将它们与一阶交换相互作用联系起来。此外，最长范围的某些参数是通过一个Pion交换势的G-Matrix元素固定的。除了对原子核特性提供相当好的描述，所产生的相互作用还导致了与天体物理计算相关的某些无限物质的显着改善。
We present a new Gogny-type finite-range effective interaction including a third Gaussian in the central term. Based on simple arguments valid for an arbitrary radial form factor, the three ranges are fixed from physical grounds, relating them to one-boson exchange interactions. Moreover, some parameters of the longest range are fixed through the G-matrix elements of the One Pion Exchange Potential. On top of giving a fairly good description of atomic nuclei properties, the resulting interaction leads to a remarkable improvement of some infinite matter properties that are relevant for astrophysical calculations.
