Abstract

The distributions of intermediate and slow neutrons from the outlet collimated channel of a photoneutron source are measured. A significant difference is observed between the shapes of the distributions of two groups of neutrons with energies above and below the cadmium cutoff. Whereas the distribution of intermediate neutrons has a symmetrical Gaussian shape, the distribution of slow neutrons has a complex shape. The possible causes of the difference between these shapes are discussed.

来自光中子源出口通道的中子和慢中子分布之间的差异

摘要对来自光中子源出口准直通道的中子和慢中子的分布进行了测量。观察到能量高于和低于镉截止点的两组中子的分布形状存在明显差异。中间中子的分布具有对称的高斯形状，而慢中子的分布则具有复杂的形状。本文讨论了造成这些形状差异的可能原因。
