光谱线

Since the splitting of the spectral lines is extremely small it cannot be detected with a conventional prism or grating spectroscope.

因为光谱线的分裂极其微小，所以它不能被常规的棱镜或者光栅分光镜检测出来。

By comparison with other experimental data we determined 42 energy levels of Cu and 13 energy levels of Ge. For the spectrum without experimental data for comparison, they are determined by isoelectronic sequence.

Applying the Large-scale multi-configuration Dirac-Fock wave functions, we calculated the parameters such as wavelength, oscillator strengths and excited energy for the transitions related to lightning spectra. The most important effects of relativity, correlation, and relaxation are included in the computational model. Comparison of the calculated results with experimental spectra shows that the spectra in plateau area have a distinctive characteristic. Beside the lines of lower excited state with n=3 in NII ions, transitions of NI and OI are increased, their excited energy is around 13~14eV, and there are rarely lines from OII ion.
