An excited heavy nucleus ${}_{Z}^{A}\mathrm{X}$ emits radiations in the following sequence: $${}_{Z}^{A}\mathrm{X} \rightarrow {}_{Z-2}^{A-4}\mathrm{D}_1 \rightarrow {}_{Z-1}^{A-4}\mathrm{D}_2 \rightarrow {}_{Z-3}^{A-8}\mathrm{D}_3 \rightarrow {}_{Z-4}^{A-8}\mathrm{D}_4 \rightarrow {}_{Z-4}^{A-8}\mathrm{D}_5$$ where $Z, A$ are the atomic and mass number of element $\mathrm{X}$, respectively. The possible emitted particles or radiations in the sequence, respectively are:
