Analysis methods to determine the bound-state beta-decay half-life of Thallium-205

Bound-state β − -decay is an exotic decay mode that produces temperature-dependent stability in nuclei. A striking example 205 Tl, part because of its impact on the Pb/ 204 Pb cosmochronometer—a short-lived ra-dionuclide clock can provide unique constraints s process material early solar system. The bound-state Tl was measured at GSI, where fully stripped 81+ ions were produced and stored Experimental Storage Ring. Decay occurred during storage producing increased daughters with time. This contribution briefly outlines experiment describes analytical corrections required to extract half-life.
