On Double-Beta Decay Half-Life Time Systematics

Recommended 2 $\beta$ (2 $\nu$) half-life values and their systematics were analyzed in the frame- work of a simple empirical approach. T${}^{2\nu }$${}_{1\mathrm{/}2}$ ~ 1/E${}^8$ trend has been observed for ${}^{128,130}$Te recommended values. This trend was used to predict T${}^{2\nu }$${}_{1\mathrm{/}2}$ for all isotopes of interest. Current results were compared with other theoretical and experimental works.
