The energy levels of Na-like ions from Copper to Molybdenum are reported. The transition wavelengths of 5g-4f, 5f-4d, 6g-4f, 6f-4d are given as well as the oscillator strengths. These transitions are of potential interest for X-ray laser. The results indicate that the 6f-4d transition of Se ions, the 6g-4f transition of Br ions, the 5f-4d transition of Zr ions, the 5g-4f transition of Nb ions are all in the range of the "Water "Window".
