Th229

WebThe Th229 nucleus possesses the lowest-energy nuclear isomeric state. Two widely accepted indirect measurements of the transition energy place it within reach of existing laser capabilities. Direct searches for the isomer deexcitation have proven elusive despite extensive effort over the past couple of decades. There is now a growing interest in … WebA benefit of the method is that it has internal traceability, usually based on the 229 Th/ 225 Ra tracer [3, 13,14]. Therefore, several methods using a-spectrometry have been proposed …
