摘要：

A study has been made of the gamma-ray and conversion-electron spectra in the decay chain 149Gd(9.4 d) --> Eu-149(93.1 d) --> Sm-149, following the electron-capture decay of 149Tb. Gamma-ray and conversion-electron emission probabilities were measured with a double-focussing magnetic spectrometer, and internal conversion coefficients, multipolarities and mixing ratios were deduced for several transitions of Eu-149 and Sm-149. These values have been compared with previously published data. Gamma-ray emission probabilities have also been measured for Sm-145, 145Pm and Nd-145, which originated via the alpha-decay branch of 149Tb.
