| Abstract: | 131Pm nucleus was produced in the 106Cd (32S,3p4n) 131Pm reaction. Theproducts were transported by helium jet and tape system, and X,γ single spectra and X-γ,γ-γ coincidence spectra were measured. The half-life of 131Pm has beendetermined to be (6.3±0.8)s. A partial decay scheme of 131Pm is proposed. |
