摘要：

We have made relativistic calculations of oscillator strengths in the isoelectronic sequence of neon for application to the modelling of x-ray laser systems. We find that the level ordering can change at certain atomic numbers, and that this is often associated with a vanishing oscillator strength in one lasing channel and an enhancement of the oscillator strength in a competing channel. It will be necessary to include the effect of plasma microfields to properly model emission spectra of a dense plasma.
