Using the multiconfiguration Dirac-Hartree-Fock (MCDHF) and the relativistic configuration interaction (RCI) methods, a consistent set of transition energies and radiative transition data for the lowest 150 states of the $3s^{2}3p^3,$ $3s3p^4,$ $3s^{2}3p^{2}3d,$ $3s3p^{3}3d,$ $3p^5,$ and $3s^{2}3p3d^2$ configurations in P-like Ge XVIII is provided. To assess the accuracy of the MCDHF transition energies, we have also performed calculations using the many-body perturbation theory (MBPT). Comparisons are made between the present MCDHF and MBPT data sets, as well as with other available experimental and theoretical values. The resulting accurate and consistent MCDHF data set will be useful for line identification and modeling purposes. These data can be considered as a benchmark for other calculations.

使用多重配置Dirac-Hartree-Fock（MCDHF）和相对论配置相互作用（RCI）方法，获得了最低的150个状态的跃迁能量和辐射跃迁数据的一致集合。 $3s^{2}3p^3，$ $3s3p^4，$ $3s^{2}3p^{2}3d，$ $3s3p^{3}3d，$ $3p^5，$ 和 $3s^{2}3p3d^2$提供了P型Ge XVIII中的构型。为了评估MCDHF跃迁能量的准确性，我们还使用多体摄动理论（MBPT）进行了计算。比较了当前的MCDHF和MBPT数据集​​，以及其他可用的实验和理论值。得到的准确和一致的MCDHF数据集将用于线路识别和建模。这些数据可以视为其他计算的基准。
