Evaluated experimental data are presented for 15 known nuclides of mass 100 (Kr, Rb, Sr, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn). Recommended values are given for level parameters, γ and β radiations, and other spectroscopic information. No excited states are known in 100Rb and 100Sn. Except for isotopic identification, no information is available for the decay of the 100Kr isotope, and limited information is known about the decay properties of the 100Sn isotope. According to Fig. 2 (A/Q versus counts plot) and as mentioned in the text in 2021Su01, 100Br isotope was not observed, although, discovery of 101Br was claimed in this work. In the case of 100Pd, the agreement in the orderings of the γ-ray cascades and γ-ray inventory between various studies of high-spin structures remains poor at high excitation energies (>9 MeV). For 100Y, the assignments of the two previously known half-lives to the respective states (g.s. and the 145-keV isomer) remain to be established. This work supersedes earlier full evaluations of A=100 by 2008Si01, 1997Si09, 1990Si05 and 1974Ko37.

A = 100的核数据表
给出了质量数为15的15种已知核素(Kr,Rb,Sr,Y,Zr,Nb,Mo,Tc,Ru,Rh,Pd,Ag,Cd,In,Sn)的评估实验数据。给出了有关物位参数,γ和β辐射以及其他光谱信息的推荐值。在100 Rb和100 Sn中没有激发态。除同位素鉴定外,没有有关100 Kr同位素衰减的信息,并且有关100 Sn同位素衰减特性的信息有限。根据图2(A / Q与计数图),如2021Su01中所述,虽然发现了101 Br,但未观察到100 Br同位素。Br被要求从事这项工作。在100 Pd的情况下,在高激发能(> 9 MeV)下,各种对高自旋结构的研究在γ射线级联和γ射线存量的排序上仍然很差。对于100 Y,两个先前已知的半衰期对相应状态(gs和145-keV异构体)的分配仍有待建立。这项工作取代了到2008Si01、1997Si09、1990Si05和1974Ko37之前对A = 100的完整评估。
