This work describes a new method for in situ measuring the lithium layer thickness. The method is based on the registration of the yield of 478 keV gamma-quanta of 7 Li(p,p'γ) 7 Li reaction. The results of measuring the radial distribution of the thickness of a lithium layer thermally deposited in vacuum on a cooled copper substrate are presented. The possibility of using this method for certification of lithium targets used for boron neutron capture therapy is noted.

原位测量锂层厚度的方法

这项工作描述了一种原位测量锂层厚度的新方法。该方法基于对7 Li（p，p'γ）7 Li反应的478 keVγ量子的产率进行记录。呈现了测量在真空中在冷却的铜基板上热沉积的锂层的厚度的径向分布的结果。指出了使用这种方法对用于硼中子俘获治疗的锂靶进行认证的可能性。
