| Abstract: | Activities of 183Os were produced by 39MeV α particles bombarding on a natural tungsten target.β+ spectrum with coincidence gate set on the strongest 382keV γ-rays of 183Os decay was measured.The endpoint energy of the β+ spectrum was determined and the QEC value of 183Os decay was extracted to be 2.24±0.10MeV which is in good agreement with the predicted value 2.30±0.10MeV on the basis of mass systematics. |
