Notes:
The effects on the plasma and other conditions required to achieve population inversions between the quantum states n=3 and n=2 of hydrogenlike ions caused by nonstatistical equilibrium fine-structure sublevel densities are examined. Collisional and radiative transitions into and out of each of the fine-structure sublevels (up to principle quantum number n=5) are taken into account in a comprehensive collisional-radiative code. Population inversions produced by both recombination and by photopumping from the 1s to 3p quantum states are examined. For electron densities Ne (approximately-less-than)1012 Z7 cm−3 (where Z is the atomic number of the hydrogenlike ion), it is shown that inversions can be much more difficult to produce than is predicted by simple calculations assuming all sublevels are populated statistically.
