In model calculation, population inversions for 2s{sup 2}2p{sup 2}3s-2s{sup 2}2p{sup 2}3p and for 2s{sup 2}2p{sup 2}d3p-2s{sup 2}2p{sup 2}3d are predicted for ions of the N-like isoelectronic sequence (Kr{sup 29+}, Zr{sup 33+}, Mo{sup 35+}, Pd{sup 39+}, Sn{sup 43+} and Xe{sup 47+}), at electron densities higher than 10{sup 22} cm{sup {minus}3}. Maximum gains of 46 cm{sup {minus}1} for Kr{sup 29+} at 245{angstrom}, and 231 cm{sup {minus}1} at 126{angstrom} for Xe{sup 47+} are obtained. The electron temperature T{sub e} is fixed at half the ionization potential for all ions. A detailed analysis shows that the mechanisms responsible for the population inversion enhancement are collisional de-excitation and radiation trapping. 16 refs., 6 figs.
