摘要: 采用结团模型(cluster model)计算了从 10752Te到292116共443个核素α衰变的半衰期，所得结果与实验值符合得很好，显示了结团模型可以成功地应用于研究原子核α衰变的性质。同时研究了Bi同位素链上奇A核α衰变的半衰期，计算结果与已有的实验值的偏差一般在3倍以内, 进而对实验上未知α衰变半衰期的原子核的性质进行了预言。这有助于将来在实验室探测与鉴别这些原子核以及研究它们的α衰变性质。理论与实验的比较将加深人们对原子核结构的认识。 The αdecay halflives of 443 nuclei are investigated within the cluster model(CM). The results are compared with the experimental data. The coincidence between theoretical results and the experimental data are satisfied， implying the CM works quite well for the study on ??decay properties. Then the adecay halflives of Bi isotopes are calculated. The results are consistent with the known experimental data. The αdecay halflives of the Bi isotopes without experimental data are predicted， which is useful for the future experimental detection and identification of these nuclei.
