用完全相对论GRASH程序计算了类Li O VI的1s2nl(n≤5)组态的最低24个精细结构能级之间的跃迁能级和辐射率。此外，使用狄拉克原子R矩阵代码，在低于63Ry的大能量范围内计算了这些能级之间跃迁的碰撞强度。为了计算有效碰撞强度，在精细能量网格中解析了共振。给出了所有跃迁的辐射率、碰撞强度和有效碰撞强度的结果。与其他可用结果进行了比较，并对本数据的准确性进行了评估。能级的精确度预计在1%以内，而其他参数可能精确度在20%以上。
Energy levels and radiative rates for transitions among the lowest 24 fine-structure levels belonging to the 1s2nl (n ≤ 5) configurations of Li-like O VI have been calculated using the fully relativistic GRASP code. Additionally, collision strengths for transitions among these levels have been computed over a wide energy range below 63 Ry, using the Dirac Atomic R-matrix Code. Resonances have been resolved in a fine energy mesh in order to calculate the effective collision strengths. Results for radiative rates, collision strengths, and effective collision strengths are presented for all transitions. Comparisons with other available results are made, and the accuracy of the present data is assessed. Energy levels are expected to be accurate to within 1%, while other parameters are probably accurate to better than 20%.
