论文摘要
核能在核天体物理学中起着核心作用，显着影响用于限制超严重物质的元素的起源和可观察物的起源。有多种技术可以满足这一需求，它们的重点是精确度和稳定性。在这里，我简要总结了飞行时间磁性依据（TOF-$bρ$）质量测量技术的状态和近乎未来的状态，并强调了与高精度质量测量方法的互补和互连性。其中包括来自TOF-$bρ$质量测量结果的最新示例，这些示例绘制了整个核领域的核结构的演变，并显着影响了天体物理模型计算的结果和解释。我还预测，可从稀有同位素束的设施中的未来测量中预计已知核质量表面的扩展。
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.
