An existing set of vibrationally resolved ionization cross section for the ground state and the first excited states of the hydrogen molecule, based on the Gryzinski method, is extended by cross sections for the isotopomeres of H₂ (i.e. D₂, T₂, HD, HT, and DT), both for non-dissociative and dissociative ionizations. The comparison of cross sections for non-dissociative ionization of H₂ with results obtained by the Molecular Convergent Close-Coupling method gives a very good agreement. The compiled tables give non-dissociative and dissociative cross sections for the ground state and the five energetically lowest electronically excited states of H₂ and its isotopomeres, in each case for the first 9 vibrational levels. Data for all vibrational levels of the excited states is available online.

基于 Gryzinski 方法的氢分子基态和第一激发态的一组现有振动分辨电离截面通过 H ₂的同位素（即 D ₂、T ₂、HD、 HT 和 DT)，均用于非解离和解离电离。H ₂非解离电离的横截面与通过分子收敛紧密耦合方法获得的结果的比较给出了非常好的一致性。汇编的表格给出了基态和 H ₂的五个能量最低电子激发态的非离解和离解横截面及其同位素，在每种情况下都是前 9 个振动能级。激发态的所有振动能级的数据都可以在线获得。
