By using the fully relativistic flexible atomic code (FAC) program to calculating the energy levels, transition probabilities, oscillator strengths, and collision strengths for Se (XXIX). These data are used in the determination of the reduced population for the 69 fine structure levels belonging to the configurations[2s2 2p2, 2s2 2p 3l (l= s, p &d) and 4l (l=s,p,d,&f)]  in C-like Se (XXIX) and gain coefficients over a wide range of electron densities (from 10+20 to 10+22cm-3) and at various electron plasma temperatures (500,1000,1500,2000,2500)eV. The results show that the transitions in Se (XXIX) ion to be the most promising laser emission lines in the XUV and soft X-ray spectral regions.
