摘要:
在介质修正的Skyrme模型框架下研究了有限核中中子-质子质量差。讨论了有限核中核子有效质量与诺伦-希弗反常之间可能的相互作用。特别是,我们发现,一个正确的描述镜像核的属性导致严格的限制可能修改的核子的有效质量的核。
英文摘要:
The neutron-proton mass difference in finite nuclei is studied in the framework of a medium-modified Skyrme model. The possible interplay between the effective nucleon mass in finite nuclei and the Nolen-Schiffer anomaly is discussed. In particular, we find that a correct description of the properties of mirror nuclei leads to a stringent restriction of possible modifications of the nucleon's effective mass in nuclei.
