研究了混合氢同位素等离子体中的Fulcher-α振子带谱。测量了H2和D2混合等离子体的光谱，并计算了D2和T2混合等离子体的光谱。在测量和计算的光谱中，观察到几个重叠。为了避免振转温度估算中的误差，需要对谱线形状进行详细的指定。冠状模型结合的拟合程序，这是不是很大程度上受到干扰的可用线的数量的减少，以评估振转温度。H2，D2和HD同位素的估计振动温度没有完全平衡，可以解释为电子碰撞和Eley-Rideal表面复合过程的组合。另一方面，旋转温度基本上处于平衡状态，并与表面温度相关。
The Fulcher-α ro-vibronic band spectra in mixed hydrogen isotope plasmas were investigated. The spectra were measured in H2 and D2 mixed plasmas as well as calculated for D2 and T2 mixed plasmas. In both the measured and calculated spectra, several overlaps were observed. In order to avoid an error in the ro-vibrational temperature estimation, detailed assignment of the spectral line shapes are reguired. The coronal model combined with a fitting procedure which is not largely disturbed by the decrease in the number of available lines was adopted to evaluate the ro-vibrational temperatures. The estimated vibrational temperatures of H2, D2, and HD isotopes were not fully equilibrated, and may be explained by a combination of the electron-impact and Eley-Rideal surface recombination processes. The rotational temperatures, on the other hand, were basically in equilibrium, and suggest a correlation with the surface temperature.
