本文研究了碰撞共振和辐射级联对类he铁（Fe XXV）谱线在1221 ~ 122能级线极化的影响。详细计算了1331l的共振对电子冲击激发率的贡献，从122l的地能级到1331l结构的各个磁亚能级。还计算了152 ~ 1331亚能级的激发碰撞强度以及1331 ~ 1331亚能级的辐射级联跃迁
The effects of collisional resonances and radiative cascades on the linear polarization of He-like iron (Fe XXV) lines from 1s2l to 1s 2 levels have been investigated. Detailed calculations have been carried out for the 1s3l3l' resonance contributions to electron-impact excitation rates from the 1s 2 ground level to the individual magnetic sublevels of 1s2l configurations. Excitation collision strengths from 1s 2 to 1s3l sublevels as well as radiative cascade transitions from 1s3l to 1s2l' sublevels have also been computed
