Within the one-level R-matrix approach several hindrance factors for a particular
radioactive decay, the emission of 20O-nuclei, have been calculated. The
interior wave functions are supposed to be given by shell model with effective residual
interactions. The exterior wave functions are calculated from a cluster-nucleus
double-folding potential obtained with the M3Y interaction. As an example of the cluster
decay fine structure, we analized the 20O-radioactivity of 255Fm.
Our results for the half-lives indicate that observation of 20O-decay would be
very difficult.
