A new tabulation of electronic factors is reported for electron conversion for elements of Z from 5 to 126 and electronic factors for electron–positron pair conversion for elements of even Z from 4 to 100. The electronic factors for electron conversion, ${\Omega }_{CE}$(E0), were calculated using a modified version of the CATAR program developed by Pauli and Raff with a relativistic-Hartree–Fock–Slater approach (Pauli and Raff, 1975). The electronic factors for electron–positron pair conversion, ${\Omega }_{IPF}$(E0), were calculated using the model developed by Wilkinson (1969). The data tables presented here cover all atomic shells up to R2 and transition energies from 1 keV to 6000 keV and from 1100 keV to 8000 keV for pair conversion. A comparison with previous electronic factor tabulations is presented. Ratios of experimental $\Omega$(E0) values for 83 E0 transitions in $8\le Z\le 98$ are compared to this tabulation. Two examples of how to use the tabulation to extract E0 strengths are also included.

对于Z元素从5到126的电子转换，已经报道了一种新的电子因子表，对于偶数Z元素的电子-正电子对转换，从4到100的电子因子表也是如此。 ${\Omega }_{CE}$（E0）是使用Pauli和Raff开发的CATAR程序的修改版，采用相对论-Hartree -Fock-Slater方法计算的（Pauli和Raff，1975）。电子-正电子对转换的电子因子，${\Omega }_{\mathrm{一世}PF}$（E0）是使用Wilkinson（1969）开发的模型计算得出的。此处显示的数据表涵盖了所有高达R2的原子壳，以及从1 keV到6000 keV以及从1100 keV到8000 keV的跃迁能，用于成对转换。提出了与以前的电子因子表的比较。实验比例$\Omega$中的83个E0转换的（E0）值 $8\le ž\le 98$与该列表进行比较。还包括有关如何使用列表提取E0强度的两个示例。
