Experimental studies will be conducted of photoionization, focussing on electron correlation as reflected in the angular distribution of photoelectrons and the alignment of the resulting ion. Measurements will be made on few electron atoms, e.g. beryllium and magnesium. Photoelectron angular distributions will be measured for the rare gases from neon to xenon. New measurements will be begun at high energy to determine the influence of higher multipoles on the angular distribution, the first such measurements using synchrotron radiation as a source.

将进行光电离的实验研究，重点是反映在光电子的角分布和所产生的离子的排列中的电子关联。测量将在几个电子原子上进行，例如铍和镁。我们将测量从氙气到氙气的稀有气体的光电子角分布。新的测量将在高能下开始，以确定更高的多极对角分布的影响，这是第一次使用同步辐射作为源进行这样的测量。
