论文摘要
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\ensuremath{^{1}Σ^{+}},v_{i}^{+}=0,\dots,27$) are reported, including in the calculation the contribution of与三个电子对称性有关的BET复合体的超级激发状态 - $^{2}π$，$^{2}σ^{+} $，以及$^{2}δ$。这些数据适用于在带有铍壁（Jet，Iter）的磁融合设备中遇到的铍和含tri虫的动力学建模。在本研究中，我们将自己限制在事件电子能量中，从10 $^{ - 3} $最高$ 2.7 $ eV，分别在$ 100 $至$ 5000 $ K之间。加上我们对Beh $^{+} $和BED $^{+} $ Systems的早期和紧密相关的研究，本工作完成了铍一氢化物离子的同位素覆盖范围。振动能（而不是振动量子态）被确定为适当的同位素相似性参数，例如，用于还原但仍具有同位素正确的血浆化学模型。
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\ensuremath{^{1}Σ^{+}},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 - $^{2}Π$, $^{2}Σ^{+}$, and $^{2}Δ$. 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 $2.7$ 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.
