A comparison of maximum likelihood (or chi-square) and Bayesian peak fitting techniques shows that the latter can reduce peak intensity uncertainties by a factor of up to ten in the case of closely separated doublets, leading to greatly improved doublet resolution. The need for laboratories to demonstrate the reliability of their chosen peak fitting techniques and measures of peak intensity is also demonstrated.

New measurements of relative gamma-ray emission probabilities in the decay of 101Mo and 101Tc are reported. Previously published conversion-electron data have been used along with the gamma-ray data to formulate self-consistent decay schemes.

Measurements of relative and absolute gamma-ray emission probabilities in the decays of Eu-154, Au-198 and Np-239 are reported. For the first two radionuclides previously published conversion-electron and beta-branching data have been used with the gamma-ray data to formulate self-consistent decay schemes.

Measurements of relative and absolute gamma-ray emission probabilities in the decays of 154Eu, 198Au and 239Np are reported.
