利用GRASP程序计算了Ti XXI的n≤ 5组态的最低49个能级中E1、E2、M1和M2跃迁的能级和辐射率。碰撞强度也计算了在很宽的能量范围内使用完全相对论DARC代码。共振在一个精细的能量网格中的阈值区域和有效的碰撞强度计算的所有1176转换温度高达10 - 7.5 K。与早期可用的，以及其他并行计算的FAC代码的比较，并指出一些过渡，特别是禁止的差异。
Energy levels and radiative rates for E1, E2, M1, and M2 transitions among the lowest 49 levels, belonging to the n≤ 5 configurations of Ti XXI, are calculated using the GRASP code. Collision strengths are also calculated over a wide energy range using the fully relativistic DARC code. Resonances are resolved in a fine energy mesh in the thresholds region and effective collision strengths are calculated for all 1176 transitions at temperatures up to 10 7.5 K. Comparisons are made with the earlier available as well as other parallel calculations from the FAC code, and discrepancies are noted for some of the transitions, particularly the forbidden ones.
