摘　　要：用能量０．８—２．ＯＭｅＶ质子束轰击元素Ｔａ、Ｌｕ使其电离，通过测量特征Ｘ射线的角分布，得到了Ｌ亚壳层原子顺排因子Ａ２和特征线Ｌｌ的极化度Ｐ，实验结果和ＰＷＢＡ理论进行了比较。基于特征偶极辐射，对原子顺排的物理图象作了解释。L3--subshell alignment and L1 line polarization of Ta and Lu induced by protons in the energy range 0. 8-2. 0MeV, has been studied by measuring the angular distribution of Lshell Characteristic x-ray. The experimental results are compared with PWSA theory. The picture of characteristic dipole redintion is discussed.
