We present a comprehensive set of vibrationally-resolved cross sections for electron-impact electronic excitation of the isotopologues of molecular hydrogen (D₂, T₂, HD, HT, and DT) initially in the ground electronic state. We apply the adiabatic-nuclei molecular convergent close-coupling (MCCC) method to calculate cross sections from threshold to 500 eV for excitation of all bound vibrational levels and dissociative excitation of the $B^{1} Σ_{u}^{+}$ , $C^{1} Π_{u}$ , $E F^{1} Σ_{g}^{+}$ , $B^{'}^{1} Σ_{u}^{+}$ , $G K^{1} Σ_{g}^{+}$ , $I^{1} Π_{g}$ , $J^{1} Δ_{g}$ , $D^{1} Π_{u}$ , $H^{1} Σ_{g}^{+}$ , $b^{3} Σ_{u}^{+}$ , $c^{3} Π_{u}$ , $a^{3} Σ_{g}^{+}$ , $e^{3} Σ_{u}^{+}$ , $d^{3} Π_{u}$ , $h^{3} Σ_{g}^{+}$ , $g^{3} Σ_{g}^{+}$ , $i^{3} Π_{g}$ , and $j^{3} Δ_{g}$ electronic states from all bound vibrational levels of the ground electronic ( $X^{1} Σ_{g}^{+}$ ) state. Including the previously-published MCCC e-H₂ cross sections (Scarlett et al., Atom. Data Nucl. Data Tables 137 (2021) 101361) the data set contains cross sections for over 60,000 electronic and vibrational transitions. The cross sections are presented in graphical form and provided as both numerical values and analytic fit functions in supplementary data files. The data can also be downloaded from the MCCC database at mccc-db.org.

分子氢及其同位素体上电子散射的完整碰撞数据集：II。H ₂同位素体的完全振动分辨电子激发（ $X^{1} Σ_{G}^{+}$ )

我们提出了一套全面的振动分辨横截面，用于最初处于基电子态的分子氢同位素（D ₂、T ₂、HD、HT 和 DT）的电子碰撞电子激发。我们应用绝热核分子会聚紧密耦合 (MCCC) 方法来计算从阈值到 500 eV 的横截面，以激发所有束缚振动能级和解离激发 $乙^{1} Σ_{你}^{+}$ , $C^{1} Π_{你}$ , $乙 F^{1} Σ_{G}^{+}$ , $乙^{'}^{1} Σ_{你}^{+}$ , $G 钾^{1} Σ_{G}^{+}$ , $一世^{1} Π_{G}$ , $J^{1} Δ_{G}$ , $D^{1} Π_{你}$ , $H^{1} Σ_{G}^{+}$ , $乙^{3} Σ_{你}^{+}$ , $C^{3} Π_{你}$ , $一种^{3} Σ_{G}^{+}$ , $电子^{3} Σ_{你}^{+}$ , $d^{3} Π_{你}$ , $H^{3} Σ_{G}^{+}$ , $G^{3} Σ_{G}^{+}$ , $一世^{3} Π_{G}$ ，和 $j^{3} Δ_{G}$ 来自地面电子的所有束缚振动能级的电子态（ $X^{1} Σ_{G}^{+}$ ）状态。包括先前发布的 MCCC eH ₂横截面（Scarlett 等人，Atom. Data Nucl. Data Tables 137 (2021) 101361），该数据集包含超过 60,000 个电子和振动跃迁的横截面。横截面以图形形式呈现，并在补充数据文件中以数值和解析拟合函数的形式提供。数据也可以从 mccc-db.org 的 MCCC 数据库下载。
