Experimental nuclear structure data from various reactions and decays are compiled and evaluated for all known nuclides with mass number A=48 (S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni). For each nuclide, detailed evaluated nuclear structure information is presented for each individual reaction and decay, and the best values combining all available data are recommended for spectroscopic properties, such as level energies, half-lives, γ-ray energies and intensities, decay radiations. No excited states have been identified in ⁴⁸S, ⁴⁸Cl, ⁴⁸Co and ⁴⁸Ni, among which the first three even have no measured ground-state half-lives and decay modes. For ⁴⁸Fe, a level scheme with a sequence of excited states was established for the first time from a recent one-neutron removal measurement by 2021Ya33. Data for excited states in ⁴⁸Ar, ⁴⁸K and ⁴⁸Mn remain limited; no decay scheme has been measured for ⁴⁸Ar and ⁴⁸K yet, while the decay scheme for ⁴⁸Ni is incomplete due to unobserved levels. ⁴⁸Ti is the most studied nuclide through various reactions and decays, followed by ⁴⁸V, ⁴⁰Ca, ⁴⁸Sc, and ⁴⁸Cr, among which no decay event to ⁴⁸Sc has been observed and the decay schemes for ⁴⁸V and ⁴⁸Cr are considered as incomplete. This work supersedes the previous full evaluations of A=48: 2006Bu08, 1993Bu04, 1985Al14, 1978Be01.

针对质量数 A=48（S、Cl、Ar、K、Ca、Sc、Ti、V、Cr、Mn、Fe、Co、Ni）的所有已知核素，对来自各种反应和衰变的实验核结构数据进行编译和评估. 对于每种核素，会针对每个单独的反应和衰变提供详细的评估核结构信息，并建议结合所有可用数据的最佳值用于光谱特性，例如能级能量、半衰期、γ射线能量和强度、衰变辐射. ^在48 S、⁴⁸ Cl、⁴⁸ Co 和⁴⁸ Ni 中没有发现激发态，其中前三个甚至没有测量到基态半衰期和衰变模式。对于⁴⁸Fe，一个具有一系列激发态的能级方案，从最近到 2021Ya33 的一次中子去除测量中首次建立。⁴⁸ Ar、⁴⁸ K 和⁴⁸ Mn激发态的数据仍然有限；尚未测量⁴⁸ Ar 和⁴⁸ K 的衰变方案，而⁴⁸ Ni 的衰变方案由于未观察到的水平而不完整。⁴⁸ Ti 是通过各种反应和衰变研究最多的核素，其次是⁴⁸ V、⁴⁰ Ca、⁴⁸ Sc 和⁴⁸ Cr，其中没有观察到⁴⁸ Sc 的衰变事件和衰变方案⁴⁸ V 和⁴⁸ Cr 被认为是不完整的。这项工作取代了以前对 A=48 的完整评估：2006Bu08、1993Bu04、1985Al14、1978Be01。
