The 198Au beta-half-life in the metal Au revisited

TL;DR

This study precisely measured the beta-half-life of 198Au at room temperature and 12 K, finding no significant temperature dependence within experimental uncertainties.

Contribution

The paper provides the most accurate measurements of 198Au's half-life at different temperatures, confirming the stability of its decay rate across these conditions.

Findings

Half-life at room temperature: 2.684 ± 0.004 days

Half-life at 12 K: 2.687 ± 0.005 days

No observable temperature dependence of the half-life

Abstract

The half-life of the beta-decay of 198Au has been measured for room temperature and 12 K. The resulting values of T(RT) = 2.684 +- 0.004 d and T(12 K) = 2.687 +- 0.005 d agree well within statistical uncertainties. An evidence for a temperature dependence of the half-life was not observed.
