Abstract：
Experimental data of complex cluster radioactivity (¹⁴C ³⁴Si) are systematically analyzed and investigated with different models. Experimental half–lives are well reproduced with a factor of 5. A new linear relationship between the decay energy of cluster radioactivity and the number of α–particle in the cluster is found. This shows that the data of cluster radioactivity provide the first experimental evidence of α–condensation near the surface of heavy nuclei.
