| Popis: | The $^{150}\mathrm{Sm}$ nucleus, populated through the $\ensuremath{\beta}$ decays of $^{150}\mathrm{Eu}^{m}$ and $^{150}\mathrm{Pm}$, was investigated by means of $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coincidence and $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ 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. |
