中子皮与中子星

Neutron Skins and Neutron Stars

J. Piekarewicz

摘要:

重核的中子皮厚度提供了与富中子物质状态方程的基本联系,从而也提供了与中子星性质的基本联系。杰斐逊实验室的铅半径实验(Prex)最近提供了第一个与模型无关的证据,证明208 Pb中存在富中子皮。在这方面的贡献,我们研究如何增加的准确性,在确定中子皮肤预期从委托强极化电子束可能会影响物理学的中子星。

英文摘要:

The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb. In this contribution we examine how the increased accuracy in the determination of neutron skins expected from the commissioning of intense polarized electron beams may impact the physics of neutron stars.
