Query: Anomalies in Radioactive Decay Rates: A Bibliography of Measurements and
  Theory   Knowledge of the decay rates (or half-lives) of radioisotopes is critical in
many fields, including medicine, archeology, and nuclear physics, to name just
a few. Central to the many uses of radioisotopes is the belief that decay rates
are fundamental constants of nature, just as the masses of the radioisotopes
themselves are. Recently, the belief that decay rates are fundamental constants
has been called into question following the observation of various reported
anomalies in decay rates, such as apparent periodic variations. The purpose of
this bibliography is to collect in one place the relevant literature on both
sides of this issue in the expectation that doing so will deepen our
understanding of the available data.
