Within the one level R-matrix approach several hindrance factors for the radioactive decays are calculated in which ¹⁴C nuclei are emitted. The interior wave functions are supposed to be given by the shell model with effective residual interactions i.e. the enlarged superfluid model (ESM). The exterior wave functions are calculated from a cluster-nucleus double-folding model potential obtained with the Michigan 3-Yukawa (M3Y) interaction. As example of the cluster decay fine structure we analysed the case of ¹⁴C-decay of ²²³Ra. Good agreement with the experimental data is obtained.
