在球对称超新星模型中，我们对集体中微子振荡进行了自洽计算，包括在“单角度”近似下的反向散射中微子（光晕效应）的影响。我们发现，由于光环效应，味道转变的开始被推到更小的半径，几公里。我们发现，在光晕效应的作用下，著名的光谱分裂现象是稳健的。
We perform a self-consistent calculation of collective neutrino oscillations including the effect of back scattered neutrinos (Halo effect) in the `single-angle' approximation, within a spherically symmetric supernova model. We find that due to the Halo effect the onset of flavor transformations is pushed to smaller radii, by a few kilometers. The celebrated phenomenon of the spectral split is found to be robust under the present inclusion of the Halo effect.
