Abstract: We present 11 independent measurements of the half-life and spectral shape ofthe 4-fold forbidden beta decay of 113-Cd using CdZnTe semiconductors with atotal combined lifetime of 6.58 kg days. Our overall result gives a half-lifeof 8.00 +- 0.11stat +- 0.24sys x 10^15 years and a Q value of 322.2 +-0.3stat +- 0.9sys keV. For the first time half-lives well beyond 10^10years have been deduced with a statistically representative sample ofindependent measurements.
