O III的电子碰撞激发
Electron Impact Excitation of O III: An Assessment
摘要：
Tayal和Zatsarinny [Astrophys。J. 850（2017）147]已经报道了类C O~III的202个能级之间跃迁的能级、辐射率（A值）、寿命和有效碰撞强度（$Υ$）的结果。对于计算，他们采用了多组态Hartree-Fock（MCHF）代码的能级和A-值，和B-样条$R$ -矩阵（BSR）代码的$Υ$。他们报告的结果涵盖了比文献中通常可用的更大范围的能级/跃迁，并且对于能级和A值似乎是准确的。然而，$Υ$的幅度和行为对于几个转换似乎不正确。我们证明了这一点，通过我们的独立计算采用灵活的原子代码（FAC），并建议一个新的计算这个重要的离子。
英文摘要：
Tayal and Zatsarinny [Astrophys. J. 850 (2017) 147] have reported results for energy levels, radiative rates (A-values), lifetimes, and effective collision strengths ($Υ$) for transitions among 202 levels of C-like O~III. For the calculations they have adopted the multi-configuration Hartree-Fock (MCHF) code for the energy levels and A-values, and B-spline $R$-matrix (BSR) code for $Υ$. Their reported results cover a (much) larger range of levels/transitions than generally available in the literature, and appear to be accurate for energy levels and A-values. However, the magnitude and behaviour of $Υ$ do not appear to be correct for several transitions. We demonstrate this through our independent calculations by adopting the flexible atomic code (FAC) and recommend a fresh calculation for this important ion.
