| 英文摘要 | Ru-89 was synthesized in the reaction of Ni-58 (Ar-36, 2p3n) on the basis of a "p-gamma" coincidence measurement by using a He-jet tape transport system, and its beta -delayed proton emission with a half-life of (1.1 +/- 0.2) s was investigated. The beta -delayed proton spectrum of Ru-89 populating the low-lying states in Mo-88 was obtained, and the final state proton branching ratios to the low-lying 2(+) and 4(+) states in Mo-88 were estimated to be 100:6. Based on the statistical model calculations, the ground state spin of (RU)-R-89 was preliminarily assigned to be 5/2(+) or 7/2(+/-), and the mass excess of Ru-89 was deduced to be -59.5 MeV. |
