摘要：

The alpha decay of mass-separated Rn-202 is studied at the ISOLDE separator. Time sequential alpha-singles spectra together with alpha-X-t and alpha-e-t coincidence events are collected. Fine structure in the alpha decay is observed and feeding of a low-lying 0(2)+ state at 816 keV in 198Po is evidenced. This 0+ state can be interpreted as the band-head of an intruder-state based deformed band, coexisting with the spherical groundstate band. Mixing between normal and intruder states is discussed. A preliminary alpha-decay study of Rn-200 did not yet reveal any fine structure.
