| 英文摘要 | The spectra shifts for the intercombination line (1s2p(p-3(1))-> 1s(2)) and the resonance line (1s2p(p-1(1))-> 1s(2)) of he-like neon, which are the two electronic dipole transitions in the k alpha group emissions, are studied under dense plasma conditions by using the self-consistent field ion sphere model. the results show the two electronic dipole transitions red shift nearly linealy with the increase of plasma electron density. moreover, the red-shift energy becomes more sensitive to the plasma electron density when the plasma electron temperature is lower. it is worthy to note that the energy discrepancy between these two spectral lines is equal to the exchange energy of state 1s2p(p-3(1)). so, it is the first time that the exchange energy varying with plasma environment is observed both qualitatively and quantitatively. this result may be useful to dense plasma diagnosis in connection with variation of the relative position and the spectral fine structure splitting in high density plasmas. |
