本文介绍了一种测定重物质中轻元素深度分布的方法。它涉及到在35 Cl束轰击下反冲的轻元素的探测。对于薄样品中存在的锂，实现了300 A的分辨率。这些测量是用1016原子/cm 2的层进行的，据估计，小到1014原子/cm 2的量可以毫不费力地定位。
A method for the determination of the depth distribution of light elements in heavy materials is described. It involves the detection of light elements recoiling under the bombardment by a 35Cl beam. A resolution of 300 A was achieved for the lithium present in a thin sample. The measures were done with layers of 1016 atoms/cm2 and it is estimated that quantities as small as 1014 atoms/cm2 can be located without much difficulty.
