A.介绍团簇放射性是原子核的自发衰变，例如-粒子，C-，Ne-，Mg或Si-原子核的发射。比粒子重的团簇的自发辐射称为奇异衰变.传统的非衰变理论可以推广到奇异衰变.在简短介绍了基本的物理模型之后，我们定义并评估了伽莫夫的衰变常数和光谱因子（本节）。在第二节中，衰变常数的模型表达式被应用到一个有代表性的异国情调的衰变样本。结果将在第三节中进一步讨论。这篇手册文章仅限于基本公式。然而，它包含了容易应用于其他衰变的所有必要信息。我们考虑了一个原子核的衰变，其中有（A + a）个核子和（Z + z）个质子
A. Introduction Cluster radioactivity is the spontaneous decay of nuclei by the emission of clusters like for example -particles, C-, Ne-, Mgor Si-nuclei. The spontaneous emission of clusters heavier than -particles is called exotic decay. The traditional -decay theory can be extended to the exotic decays. After a short presentation of the underlying physical model we de ne and evaluate Gamow's decay constant and the spectroscopic factor (this section). In Section II the model expression for the decay constant is applied to a representative sample of exotic decays. The results are further discussed in Section III. This handbook article is restricted to the basic formulae. It contains, however, all information necessary for the easy application to other decays. We consider the decay of a nucleus with (A + a) nucleons and (Z + z) protons
