THE PREDICTION OF THE HINDRANCE FACTORS FOR THE 20O-CLUSTERTRANSITION OF 255Fm WITHIN THE ENLARGED SUPERFLUID MODEL

[摘要] Within the one-level R-matrix approach several hindrance factors for a particularradioactive decay, the emission of ²⁰O-nuclei, have been calculated. Theinterior wave functions are supposed to be given by shell model with effective residualinteractions. The exterior wave functions are calculated from a cluster-nucleusdouble-folding potential obtained with the M3Y interaction. As an example of the clusterdecay fine structure, we analized the ²⁰O-radioactivity of ²⁵⁵Fm.Our results for the half-lives indicate that observation of ²⁰O-decay would bevery difficult.
