Experimental spectroscopic data on nuclear structure and decay are evaluated for known nuclides of mass 98 (Br, Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In). Detailed evaluation results of individual reactions and decays are presented together with the Adopted values that are recommended for level properties, γ and β radiations, and other spectroscopic information. ⁹⁸Mo remains as the most extensively studied nuclide via various reactions and decays. Level schemes of Sr, Y, Zr, Tc, and Pd nuclides in this mass chain are also well established to date; while Kr, Rb, Nb, Ag and Cd are amongst the least-studied ones for excited states, with only limited data available for each. On the neutron-rich side, ⁹⁸Br has been identified in the ⁹Be(²³⁸U,F) reaction, but no spectroscopic data are yet available, while for ⁹⁸In on the proton-rich side, only the ground state and an isomer are known with half-lives measured but their spin-parities and the absolute level energy of the isomer yet to be determined. While ⁹⁸Ru and ⁹⁸Rh have also been extensively studied, large discrepancies exist between the high-spin sections of the proposed level schemes in different measurements, and these need to be clarified and resolved with further experimental investigations to improve the currently-adopted ones, which have been selected from the measurements with higher statistics, considering no other criteria of preference. This work supersedes all the earlier evaluations of A=98 (2003Si07, 1998Si18, 1992Si21, 1983Mu21, 1974Me34).

对于已知质量为98的核素（Br，Kr，Rb，Sr，Y，Zr，Nb，Mo，Tc，Ru，Rh，Pd，Ag，Cd，In），对核结构和衰变的实验光谱数据进行了评估。给出了各个反应和衰变的详细评估结果，以及针对物位特性，γ和β辐射以及其他光谱信息推荐的采用值。通过各种反应和衰变，⁹⁸ Mo仍然是研究最广泛的核素。迄今为止，该质量链中Sr，Y，Zr，Tc和Pd核素的能级方案也已建立。而Kr，Rb，Nb，Ag和Cd处于受激状态研究最少的状态中，每种状态的数据都很有限。在富中子方面，⁹⁸在⁹ Be（²³⁸ U，F）反应中已鉴定出Br ，但尚无光谱数据，而对于富质子侧的⁹⁸ In，只有基态和异构体已知，具有半衰期，但它们的自旋奇偶性和异构体的绝对能级尚未确定。而⁹⁸ Ru和⁹⁸Rh还经过了广泛的研究，在不同的测量条件下，建议的液位方案的高旋转部分之间存在较大差异，需要对这些问题进行澄清和解决，以进行进一步的实验研究以改善当前采用的方法，该方法已从在不考虑其他优先选择标准的情况下，以较高的统计数据进行测量。这项工作取代了A = 98的所有早期评估（2003Si07、1998Si18、1992Si21、1983Mu21、1974Me34）。
