摘要
用68 MeV的^(16)O束轰击2 mg/cm^2的^(106)Cd靶产生^(120)Ba再把它氟化,送入氦喷嘴离子源。在线质量分离的^(120)Ba的衰变性质被γ-γ,γ-γ和γ-β符合测量。其半衰期为24±2S,总衰变能Q_(EC)=5.0±0.3MeV,并获得了简单的^(120)Ba的衰变纲图。
^(120)Ba was produced by 68MeV ^(16)O beam bombarding a 2mg/cm^2 thick ^(106)Cd target
and fluorated in a halium-jet ion source. The decay of on-line mass separated
activity ^(120)Ba has been studied by γ-X, γ-γ γ-β coincidence measurements. Its half-
life was measured to be 24±2s. The total decay energy was extracted to be Q_(EC)=
5.0±0.3 MeV. A simple decay scheme has been proposed.
