DETERMINATION OF LITHIUM CONTENT IN SOLIDS BY NUCLEAR REACTION TECHNIQUE
DOI: 10.17804/2410-9908.2020.4.028-034 The acceleration method of nuclear reactions is used to measure the content of lithium and oxygen in zirconium oxides. The purpose of the study stems from the fact that there are no direct methods for determining lithium concentration in solids, while lithium is currently widely used for alloying alloys in aircraft construction, nuclear power engineering, electrochemical devices, and other fields of technology. It is shown that satisfactory metrological characteristics of the method are provided when using the 6Li(d, p0)7Li and 7Li(d, p)8Li reactions at a deuteron energy of 650 keV.
