入射辐射对Te = 100 eV的超导体非LTE谱的影响
Effect of incoming radiation on the non-LTE spectrum of Xe at Te = 100 eV
摘要：
在碰撞辐射模型的框架内，利用HULLAC程序，研究了电子温度为100 eV时，稀释普朗克辐射场对氘代气体的影响。原子模型跨越19个电荷态，包括20 375个组态，包含超过2个10^6能级。我们用混合UTA模型模拟了包含超过10^9个跃迁的详细光谱。辐射温度Tr从0变化到1.5Te。用于减小辐射场的稀释因子D在固定Tr = Te下从0独立地变化到3。在这两种情况下，平均电荷状态Z* 从15增加到27，但是以不同的方式。它表明，即使稀释D = 0.01改变Z* 超过1.5。Tr和D的不同组合产生完全相同的Z*，可能会产生足以观察到的不同的线比。这个事实可以用辐射场的形状和原子结构的相互作用来解释。
英文摘要：
The effect of a diluted Planckian radiation field on a Xe gas at the electron temperature of 100 eV is investigated within the framework of a Collisional Radiative Model, using the HULLAC code. The atomic model spans 19 charge states, includes 20 375 configurations and contains more than 2 10^6 levels. We have simulated detailed spectra comprising more than 10^9 transitions with the Mixed UTA model. The radiation temperature Tr is varied from 0 to 1.5 Te. The dilution factor, D, applied to decrease the radiation field, is varied independently from 0 to 3 at fixed Tr = Te. In both cases, the average charge state Z* increases from 15 to 27, but in different ways. It is shown that even a dilution D = 0.01 changes Z* by more than 1.5. Different combinations of Tr and D yielding exactly the same Z*, may give line ratios sufficiently different to be observed. This fact is explained by the interplay of the shape of the radiation field and the atomic structure.
