Gain coefficients.are calculated for neon-like gallium and germanium ions. s.orter wavelengths.are calculated and predicted to be emitted. The gain coefficients.are calculated among 457 energy levels.of the neon-like ions. Collis.onal excitations.were calculated through the dis.orted wave approximations.through five electron temperatures.Ts.b>es.b> = 300, 500, 700, 1000 and 1500 eV.
