有一个科学术语叫做半衰期(half life)。例如,铀238的半衰期约为45亿年,意思就是,每过45亿年,一个U-238原子核会有一半的概率衰变。有一个著名的射击游戏叫做《半条命》,其实这个游戏的英文名是half life,本意就是“半衰期”,所谓“半条命”实际上是望文生义的误译。为了帮助大家理解这个概念,美国韦尔斯利学院(...
The half-life of Ne-18 has been determined by detecting 1042-keV gamma rays in the daughter F-18 following the superallowed-Fermi beta(+) decay of samples implanted at the center of the 8 pi gamma-ray spectrometer, a spherical array of 20 HPGe detectors. Radioactive Ne-18 beams were pr...
An effective and feasible method which is used to measure half-life of short-lived nuclei is described. The half-life of the nuclide /sup 26/P was measured and the result is 20/sup +35//sub /minus/15/ ms. The observed half-life is in good agreement with theoretical calculation.关键...
摘要: Liquid-scintillation counting techniques have been applied to the measurement of the specific activity and the beta spectrum of the natural radioactivity of rubidium. The measured Rb 87 half-life is (47.0±1.0)× 10 9 yr, and the observed maximum beta energy is 272±3 kev....
