线核 meaning in English

line core

The contribution to the giant resonances from the currents of vector mesons are also examined , it shows that currents of vector mesons play an important role in collective giant resonances . by studying the properties of collective multipole excitations of nuclei , a general conclusion is that those effective lagrangians recently developed can well describe not only the nuclear ground state properties of finite nuclei , stable and unstable ones up to the nuclei drip lines , but also the collective excited states and giant resoancnes in doubly closed shell nuclei
通过对核的电多极巨共振性质的研究，我们发现现有的这些非线性的有效相互作用不但能够很好地描述有限核的基态性质，包括球形和变形核以及远离稳定线核，而且对一些双满壳核的集体激发态和巨共振性质也能进行合理地解释，包括巨共振峰的位置和中心能量。
