Abstract All available experimental data of nuclear structure and decay are evaluated for the known nuclides of mass 38 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed results of this evaluation are presented with the best values recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic information. The 38Ar nuclide remains as the most extensively studied via various reactions and decays; no excited states are known in 38Al except for that an isomeric state is tentatively proposed from a recent β-decay measurement (2015St14); the 38Sc and 38Ti nuclides remain unidentified, with no experimental references reported for 38Sc and with a measurement of fragmentation cross sections reported for 38Ti but finding no evidence of its presence (1996Bl21). This work supersedes the earlier full evaluation of A=38 by J.A. Cameron and B. Singh (2008Ca01).

A=38 的核数据表

摘要 对已知质量为 38 的核素（Mg、Al、Si、P、S、Cl、Ar、K、Ca、Sc、Ti）的核结构和衰变的所有可用实验数据进行了评估。该评估的详细结果以能级能量、半衰期、γ 射线能量和强度、衰变特性（辐射的能量、强度和位置）以及其他光谱信息的最佳推荐值呈现。38Ar 核素仍然是通过各种反应和衰变进行最广泛研究的；除了最近的 β-衰变测量（2015St14）暂时提出了异构状态外，在 38Al 中没有已知的激发态；38Sc 和 38Ti 核素仍未确定，没有关于 38Sc 的实验参考报告和关于 38Ti 的碎片横截面测量报告，但没有发现其存在的证据 (1996Bl21)。这项工作取代了 JA Cameron 和 B. Singh (2008Ca01) 早期对 A=38 的全面评估。
