| Description | Journal: Journal of Physics B: Atomic, Molecular and Optical Physics We show that for configurations of the type $3p^{M}3d^{N}$ the influence of core excitations, in particular the excitation $3p^{2}$ to $3d^{2}$, is important both for energies and oscillator strengths. The latter is particularly true for transitions of the type $3p^{6}3d^{N}$ to $3p^{5}3d^{N+1}$ due to the fact that the core excitation in the ground configuration leads to a configuration which has an allowed dipole transition to the excited state. Differences and similarities between $3p^{5}3d^{N}$ and the more extensively studied $3p^{6}3d^{N}$ configurations are pointed out and illustrated with several examples concerning highly charged ions. The conclusion is that, while core excitations are important for the description of transitions out of the open 3d shell, they are absolutely essential for transitions out of the closed 3p shell, gf values are given for astrophysically important transitions in Ni X. |
