Abstract: In this paper, we assume difference between experimental and HFR theoretical energy level values can be fitted into function \Delta E=A+B Z_c+C Z_c^2+D Z_c^3+E Z_c^4+F /\left(Z_c+G\right). With experiment results that can be acquired now, we calculate energy level values, wavelengths of 3 \mathrm~d-4 \mathrmp, 4 \mathrm~s-4 \mathrmp, 4 \mathrmp-4 \mathrm~d in Kr IX-Rh XXIII and also give out HFR theoretical oscillator strengthes for every spectral lines.
