Oscillator strengths for transitions in singly ionized copper

We present the first extensive calculation of oscillator strengths for oute r shell transitions in singly ionized copper using both an LS-coupling appr oximation and a relativistic approach. Energy levels and details of the com positions of states are also included as are transition probabilities. Part icular attention has been paid to correlation in the open 3d shell and the need to allow for different 3d radial functions in different states. This i s achieved through the use of an extensive set of correlation configuration s constructed from a large orbital basis set. This set includes pseudo orbi tals whose purpose is either to correct the 3d function for states with the 3d shell filled to different levels or to introduce specific correlation e ffects into the calculation.
