Energy levels and transition rates for electric-dipole, electric-quadrupole, magnetic-dipole, and magnetic-quadrupole transitions among the levels arising from the $n\le 5$ configurations in Al-like Cu XVII are calculated respectively by two state-of-the-art methods, namely, the Multi-Configuration Dirac–Hartree–Fock approach and the second-order many-body perturbation theory. Our results are compared with available experimental and other theoretical values. In addition, effective collision strengths of direct excitation between these levels are provided using the distorted wave approximation. Several line pairs are pointed out that might be useful for density diagnostics.

类铝XVII的能级和跃迁速率

电偶极子，电四极子，磁偶极子和磁四极子跃迁的能级和跃迁速率由 $ñ\le 5$通过两种最先进的方法，即多构型狄拉克—哈特里—福克方法和二阶多体摄动理论，分别计算出铝样Cu XVII中的构型。我们的结果与可用的实验值和其他理论值进行了比较。另外，使用失真波近似提供了这些水平之间直接激励的有效碰撞强度。指出了几条可能对密度诊断有用的线对。
