The Livermore X-ray Laser experiments in 1984 have shown the existence of Neilke 3p-3s population inversions in a collisional Se plasma (Z=34) with significant gains (5 cm-1). We have focused our efforts on the behavior of the gains along the target neon isoelectronic sequence. This study implies the determination of the Z-dependance of the rate coefficients of all the involved atomic processes : collisional excitation (C). radiative decay (A) and dielectronic recombination (αd). Thus we use atomic structure and electron-ion collisional codes (SUPERSTRUCTURE. Distorted Waves. AUTOLSJ and JJOM) . The different calculations have been done on a large selection of ions, from Ar to Ag. They include relativistic effects in a fine structure scheme. The z-dependance of the numerical results is expressed as polynomial or rational forms.
