使用 R 矩阵方法研究了低能电子碰撞中的共振，研究了八种总对称性： ，键长范围为 0.8 到 。丰富而复杂的共振结构是显而易见的。在可能的情况下，使用更合适的本征相位和和时间延迟方法来拟合谐振。位置和宽度被制成表格。导出各个共振态的电势曲线并将其用于核运动计算。与实验的良好一致性使得可以对低于 13 eV 的所有共振进行解释和分配，而在此之前，不同的实验和理论之间存在混淆和矛盾。
Resonances in low-energy electron- collisions are studied using the R-matrix method for eight total symmetries: , over a range of bond lengths from 0.8 to . A rich and complicated structure of resonances is apparent. Where possible, the resonances are fitted using the more appropriate of the eigenphase sum and time-delay methods. Positions and widths are tabulated. Potential curves of individual resonant states are derived and used for nuclear motion calculations. Excellent agreement with experiment has allowed the explanation and assignment of all the resonances below 13 eV where previously there had been confusion and contradiction among different experiments and theory.
