Description
Yrast and near yrast states have been investigated in 210Rn to high spin (J > 30) and high energy (10 MeV). Three different (HI, xn) reactions were used to populate the states of interest and several different γ-ray spectroscopic techniques were utilized. Three high spin yrast traps were discovered. Two de-excite by strong E3 transitions while the third decays mainly via an extremely inhibited E2 transition. The E3 decays are interpreted as allowed single particle transitions between proton or neutron states above the 208Pb shell closure while the inhibited E2 transition is interpreted as indicating a substantial change in structure as the decay proceeds down the yrast line. Interpretation has been given in terms of shell model calculations
