| 英文摘要 | Proton emission from Tm-145 was observed for the first time via the Mo-92(Ni-58,p4n) reaction, using the Holifield Radioactive Ion Beam Facility Recoil Mass Spectrometer in conjunction with a double-sided Si strip detector at the focal plane. The measured energy of the emitted proton is 1.728(10) MeV and its half-life is 3.5(10) mu s, the shortest ever observed for ground-state proton radioactivity. When compared to the calculated WKB half-life for an l=5 transfer, the spectroscopic factor is 0.51(16), which is consistent with the value of 0.64 calculated via the BCS approximation for a spherical nucleus. Also, the half-life of Cs-113 was determined with a greater precision than previously available to be 16.7(7) mu sec. |
