摘要: A new model is proposed for the mechanism of cluster formation and then penetration confining nuclear interaction barrier in radioactive nuclei. The treated as a quantum-mechanical fragmentation process WKB penetrability found analytically. Applications are made to /sup 14/C decay 222-224/Ra 24/Ne 232/U. branching ratio 232/U also calculated be incredibly small compared that its decay.
