绘制核质量表面边界图

Mapping the frontiers of the nuclear mass surface

Zach Meisel

摘要:

核质量在核天体物理学中起着核心作用,对用于约束超密度物质的元素和可观测量的起源产生重大影响。有各种各样的技术可以满足这一需求,它们对精度和稳定性的强调各不相同。本文简要介绍了飞行时间磁刚性(TOF- $Bρ$)质量测量技术的现状和发展前景,强调了其与高精度质量测量方法的互补性和相互联系性。这包括TOF- $Bρ$质量测量的最新实例,这些实例绘制了整个核景观中原子核结构的演变,并对天体物理模型计算的结果和解释产生了重大影响。我还预测了预期的扩张,在已知的核质量表面从未来的测量设施的稀有同位素束。

英文摘要:

Nuclear masses play a central role in nuclear astrophysics, significantly impacting the origin of the elements and observables used to constrain ultradense matter. A variety of techniques are available to meet this need, varying in their emphasis on precision and reach from stability. Here I briefly summarize the status of and near-future for the time-of-flight magnetic-rigidity (TOF-$Bρ$) mass measurement technique, emphasizing the complementary and interconnectedness with higher-precision mass measurement methods. This includes of recent examples from TOF-$Bρ$ mass measurements that map the evolution of nuclear structure across the nuclear landscape and significantly impact the results and interpretation of astrophysical model calculations. I also forecast expected expansion in the known nuclear mass surface from future measurement at the Facility for Rare Isotope Beams.
