Determination of lithium by reactor activation analysis using the reaction chain:6Li(n,t)4He;32S(t,n)34mCl

The occurrence, in a nuclear reactor, of the reaction chain:⁶Li(n,t)⁴He;³²S(t,n)^34mCl has been experimentally established. Experimentation for its application to the activation analysis determination of lithium has been carried out, and a radiochemical method for separation of^34mCl is presented. The sensitivity is 0.4 g for the following conditions; 15 min irradiation (thermal flux: 1.5·10¹³ n·cm^–2·s^–1); 30 min decay; 2,000 s measurement (semiconductor detector).
