最近Libby等通过对铁陨石的元素丰度分析,发现元素在(Ga、Ge、As)、(Ru、Rh、Pd)和(Os、Ir、Pt)三处的实测丰度值大大超过理论预期值。他们认为这是超重元素Z=107-114裂变引起的,通过分析,得到最长的半衰期τ_(1/2)=10~8年。Flerov等对碳质球粒陨石的元素丰度分析后,得到超重元素Z=114的τ_(1/2)=1.6×10~8年。我们在计算元素起源时发现,第三个r-峰(A~195)和第三个s-峰(A~208)的丰度应当相近。但
Recently, Libby and his colleagues analyzed elemental abundances of iron meteorites and found that the measured abundances of elements at (Ga, Ge, As), (Ru, Rh, Pd) and (Os, Ir, Pt) value. They think this is caused by the fission of the overweight element Z = 107-114. By analysis, the longest half-life τ_ (1/2) = 10 ~ 8 years is obtained. After analyzing the elemental abundance of carbonaceous chondrites by Flerov et al., The τ_ (1/2) of overweight element Z = 114 = 1.6 × 10 ~ 8 years was obtained. We calculated the origin of the element and found that the abundances of the third r-peak (A ~ 195) and the third s-peak (A ~ 208) should be similar. but
