标题： Compressibility of Nuclear Matter from Shell Effects in Nuclei

摘要： 核物质的压缩性在过去十年中受到了广泛关注，各种方法已被用于提取这一物质的基本性质。 最近，相对论和非相对论计算的呼吸模式巨单极共振（GMR）结果之间出现了显著差异。 这是由于对GMR动力学的理解不足，以及对其与无限核物质压缩模量确切关系的认识不足。 在此，我提出了一种基于核壳效应的替代方法。 壳效应已知在粒子分离能方面以极高的精度表现出来。 在非相对论密度依赖的Skyrme理论框架内，显示了核物质的压缩性对核中壳效应有显著影响。 显示了2个中子分离能和因此而来的经验壳效应可以用来约束核物质的压缩性。 显示英文摘要

摘要： The compressibility of nuclear matter has received significant attention in the last decade and a variety of approaches have been employed to extract this fundamental property of matter. Recently, significant differences have emerged between the results of relativistic and non-relativistic calculations of breathing mode giant monopole resonance (GMR). This is due to a lack of understanding of the dynamics of GMR and of its exact relationship to the compression modulus of the infinite nuclear matter. Here, I present an alternative approach based upon nuclear shell effects. The shell effects are known to manifest experimentally in terms of particle-separation energies with an exceedingly high precision. Within the framework of the non-relativistic density-dependent Skyrme theory, it is shown that the compressibility of nuclear matter has a significant influence on shell effects in nuclei. It is shown that 2-neutron separation energies and hence the empirical shell effects can be used to constrain the compressibility of nuclear matter.
