摘要：

The Sm-150 nucleus, populated through the beta decays of Eu-150(m) and Pm-150, was investigated by means of gamma-gamma coincidence and gamma-gamma angular correlation studies using an array of 20 Compton-suppressed Ge detectors. The study particularly focuses on the determination of weakly populated levels and weak decay branches between established levels. A weakly populated state at 1603 keV is established to have spin-parity 0(+) from the angular correlation data; a second weakly populated state at 1786 keV is confirmed to have spin-parity 0(+) on a similar basis.
