Effects of oscillator strength transfer and radiative decay cancellation in Ne-like and Ni-like sequences. Application to X-ray laser modeling and plasma diagnostics

摘要

We have made relativistic calculations of energy levels and oscillator strengths in the isoelectronic sequences of neon and nickel. We investigate oscillator strength anomalies in both sequences and find that they are extremely sensitive to external perturbations. It will be necessary to include the effect of plasma microfield to properly model emission spectra of dense plasma.
