There are expected relatively strong spectral lines of helium- and hydrogenlike- nitrogen ions in this region, if the nitrogen plasma is heated up to 40-80 eV. Plasma heating by the capillary Z-pinch is presumed. Spatial and time evolutions of pinching plasma quantities are modeled by means of RHMD Z* engine code for our current experimental set up. Under selected experimental conditions the power of radiation estimated in the spectral range 2.1 – 3.1 nm is remarkably higher than that in the spectral range 13 - 14.3 nm. Detail kinetics of nitrogen ions in the plasma was further evaluated by FLY code used as a post -processor. Instantaneous spectra were evaluated and the spectral line with the wavelength 2.88 nm prevails under optimized experimental conditions.
