Rate coefficients for the dissociative recombination, vibrational excitation and vibrational de-excitation of the BeT${}^{+}$ ion for all vibrational levels of its ground electronic state ($X^1{\Sigma }^{+},v_i^{+}=0,\dots ,27$) are reported, including in the calculation the contribution of super-excited states of the BeT complex pertaining to three electronic symmetries - ${}^2\Pi$, ${}^2{\Sigma }^{+}$, and ${}^2\Delta$. These data are suitable for the kinetic modeling of beryllium and tritium containing plasma, as encountered in magnetic fusion devices with beryllium walls (JET, ITER). In the present study we restrict ourselves to incident electron energies from 10⁻³ up to $2.7\mathrm{eV}$, and to electron temperatures between 100 and 5000 K, respectively. Together with our earlier and closely related studies on the BeH${}^{+}$ and BeD${}^{+}$ systems, this present work completes the isotopic coverage for the beryllium monohydride ions. The vibrational energy (rather than the vibrational quantum state) is identified as a proper isotopic similarity parameter, e.g., for reduced but still isotopically correct plasma chemistry models.

BeT的解离重组，振动激发和振动去激的速率系数${}^{+}$ 离子处于其基态电子状态的所有振动水平（$X^{\mathrm{1个}}{\Sigma }^{+}，v_{\mathrm{一世}}^{+}=0，\dots ，27$），包括在计算中BeT配合物的超激发态对三种电子对称性的贡献- ${}^{\mathrm{2个}}\Pi$， ${}^{\mathrm{2个}}{\Sigma }^{+}$， 和 ${}^{\mathrm{2个}}\Delta$。这些数据适用于含铍和tri的等离子体的动力学建模，如在带有铍壁的磁聚变设备（JET，ITER）中遇到的那样。在本研究中，我们将入射能量限制在从10 ^-3到最大$\mathrm{2个}。7\mathrm{电子伏特}$，电子温度分别介于100和5000 K之间。连同我们之前和与BeH密切相关的研究${}^{+}$ 和BeD${}^{+}$系统中，本工作完成了一氢化铍离子的同位素覆盖。振动能（而不是振动量子态）被识别为适当的同位素相似性参数，例如，用于减少但仍是同位素正确的等离子体化学模型。
