The half-life of Au-198: High-precision measurement shows no temperature dependence Academic Article

abstract

• We have measured the half-life of the -decay of 198Au in a metallic environment, both at low temperature (19K), and also at room temperature. We find the half-lives at both temperatures to be the same within 0.04%, a finding that contradicts a recent report of a 3.61.0 % difference in the 198Au half-life when measured at essentially the same two temperatures. Our results for the half-life, 2.69490.0009 d at room temperature and 2.69530.0008 d at 19K, also agree well with previous precision room temperature measurements. 2008 Societ Italiana di Fisica and Springer-Verlag.
