摘要:

在色球层中形成的Sc Ⅱ 4247 A线与Na Ⅰ D_2和Ba Ⅱ D_2一样,具有明显的Q/I三重峰结构和量子干涉效应。我们试图用F态干涉理论研究这种三峰结构的性质,包括部分频率重分布(PRD)的影响。和辐射转移(RT)。我们将我们的结果与在太阳边缘附近的一个安静区域所作的观测进行了比较。尽管考虑了PRD和RT效应,但仍无法重现Q/I中观察到的三峰结构。虽然可以再现两个翼PRD峰(在中心峰的任一侧)和近翼连续区,但中心峰被由超精细结构分裂产生的增强的去极化完全抑制。这种抑制仍然适用于所有测试的广泛不同的1D模型大气或它们的任何多组分组合。虽然多维辐射转移效应可以改善强度分布的拟合,但它们似乎不能解释神秘的中心Q/I峰。这使我们怀疑量子物理学的某些方面缺失了。

英文摘要:

The Sc II 4247 A line formed in the chromosphere is one of the lines well known, like the Na I D_2 and Ba II D_2, for its prominent triple peak structure in Q/I and the underlying quantum interference effects governing it. In this paper, we try to study the nature of this triple peak structure using the theory of F-state interference including the effects of partial frequency redistribution (PRD) and radiative transfer (RT). We compare our results with the observations taken in a quiet region near the solar limb. In spite of accounting for PRD and RT effects it has not been possible to reproduce the observed triple peak structure in Q/I. While the two wing PRD peaks (on either side of central peak) and the near wing continuum can be reproduced, the central peak is completely suppressed by the enhanced depolarization resulting from the hyperfine structure splitting. This suppression remains for all the tested widely different 1D model atmospheres or for any multi-component combinations of them. While multidimensional radiative transfer effects may improve the fit to the intensity profiles, they do not appear capable of explaining the enigmatic central Q/I peak. This leads us to suspect that some aspect of quantum physics is missing.
