Calculations of population inversion due to transitions in multiply charged neon-like ions in the 200-2000 $\mathring{A}$

A radiative collisional model which allows for all the levels of the $1s^22s^22p^53s$, $2p^53p$ and $2p^53d$ configurations is used to calculate the populations of the first excited states of neon-like ions. An earlier conclusion that an inversion exists between levels of the lp $2p^53p$ and $2p^53s$ configurations in a stationary plasma is confirmed. It is shown that an inversion with a fairly high gain is due to not one but several types of transitions covering a wide wavelengths range.
