The rapid proton capture process (rp-process) is believed to be responsible for energy production and the synthesis of elements in X-ray bursts. Although understanding the \((p,\gamma )\)–\((\gamma ,p)\) equilibrium for a wide range of masses during the process is essential, it is hampered by the large uncertainties of several key isotopes participating in the rp-process. In the present work, we investigate the impacts of mass uncertainties on \((p,\gamma )\)–\((\gamma ,p)\) equilibria in the rp-process, which strongly affects the reaction paths, the isotopic abundances of nuclei with \(A > 65\), the effective lifetimes of waiting points, and the luminosity of X-ray bursts. The results show that current mass uncertainties still result in rather large deviations up to two orders of magnitude in many astrophysical photodisintegration rates. The numbers of isotopes and the values of the mass resolving power required for precise mass measurements using the multi-reflection time-of-flight (MR-TOF) technique are estimated for future experiments at modern radioactive ion beam facilities, including the RAON in Korea.

快速质子俘获过程 ( rp -process) 被认为是 X 射线爆发中能量产生和元素合成的原因。尽管在此过程中了解各种质量的\((p,\gamma )\) – \((\gamma ,p)\)平衡是必不可少的，但它受到参与的几个关键同位素的巨大不确定性的阻碍。在RP -Process。在目前的工作中，我们研究了质量不确定性对rp 过程中\((p,\gamma )\) – \((\gamma ,p)\)平衡的影响，这强烈影响了反应路径，同位素具有\(A > 65\)的原子核丰度、等待点的有效寿命和 X 射线爆发的光度。结果表明，当前的质量不确定性仍然导致许多天体物理光解体速率存在高达两个数量级的较大偏差。使用多反射飞行时间 (MR-TOF) 技术进行精确质量测量所需的同位素数量和质量分辨能力值是为未来在现代放射性离子束设施（包括韩国的 RAON）上的实验而估算的.
