Experimental nuclear spectroscopic data are evaluated for 12 known nuclides of mass number=71 (Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Kr). Detailed compiled and evaluated information is presented for each reaction and decay experiment. The β⁻n decay of ⁷²Co to ⁷¹Ni is included in this work, while for β⁻n decay of ⁷¹Co to ⁷⁰Ni, consult Nuclear Data Sheets for A=70 (2016Gu11) or the ENSDF database for ⁷⁰Ni. Combining all the available data, recommended values are provided for energies, spins and parities, and half-lives of levels, with energies, branching ratios and multipolarities of γ radiations, and characteristics of β and α radiations in radioactive decays. Excited-states have not yet been identified in ⁷¹Mn, ⁷¹Fe, and ⁷¹Kr, with the ground-state half-life remaining unknown only for ⁷¹Mn; data for excited states in ⁷¹Co and ⁷¹Ni are very limited; ⁷¹Ga, ⁷¹Ge and ⁷¹As are the most extensively studied nuclides via various reactions and decays, followed by ⁷¹Cu, ⁷¹Zn, ⁷¹Se, and ⁷¹Br, however, except for ⁷¹Ge, the decay schemes of all other nuclides are considered as incomplete due to a large gap between the decay Q-value and the highest observed level. This work supersedes earlier evaluations of A=71 by 2011Ab01.

对质量数 = 71 的 12 种已知核素（Mn、Fe、Co、Ni、Cu、Zn、Ga、Ge、As、Se、Br、Kr）的实验核光谱数据进行了评估。为每个反应和衰变实验提供了详细的编译和评估信息。⁷² Co 到⁷¹ Ni 的β ^- n 衰变包含在这项工作中，而对于⁷¹ Co 到^{70 Ni 的}β ^- n 衰变，请查阅 A=70 (2016Gu11) 的核数据表或⁷⁰ Ni的 ENSDF 数据库。结合所有可用数据，提供了能量、自旋和宇称、能级半衰期的推荐值，以及γ的能量、分支比和多极性辐射，以及放射性衰变中β和α辐射的特性。尚未确定⁷¹ Mn、⁷¹ Fe 和^{71 Kr 的激发态，只有71} Mn 的基态半衰期仍然未知；⁷¹ Co 和⁷¹ Ni的激发态数据非常有限；⁷¹ Ga、⁷¹ Ge 和⁷¹ As 是通过各种反应和衰变得到最广泛研究的核素，其次是⁷¹ Cu、⁷¹ Zn、⁷¹ Se 和^{71 Br，但71}除外Ge，所有其他核素的衰变方案被认为是不完整的，因为衰变 Q 值和最高观测水平之间存在很大差距。这项工作取代了 2011Ab01 之前对 A=71 的评估。
