摘要: We analyze the alpha-decay fine structure to excited 0(2)(+) states in Hg and Rn isotopes. These are described as minima potential energy surface (PES) provided by standard deformed Woods-Saxon plus pairing approach. also investigate alpha decay from state P(0(2)(+)) parent nucleus evaluating corresponding hindrance factor (HF). By analyzing experimental HF's we find remarkable property that ground D(0(1)(+)) D(0(2)(+)) daughter nuclei occupied with almost equal probabilities if there is no P(0(+)) nucleus. Moreover, exists an then occupation probability of this 25%.
