Abstract : In this report we present the results of our search for lasing schemes using a collisional pumping mechanism of active level population suitable for a capillary discharge plasma. We have performed atomic data calculations which give us accurate figures for energy level positions for Ne- like Ar, including highly excited levels which have not been studied experimentally and which are of significant interest for short-wavelength lasing. We also calculated radiative transitions probabilities as well as branch coefficients for transitions of interest for lasing. The calculations were performed not only for Ne-like ions but also for Ni-like ions of krypton and molybdenum, as the Ni-like scheme seems to be promising for scaling to lower wavelengths. Using the results of these calculations, we are able to predict possible laser lines and to estimate their relative intensities.
