High-spin States in²¹⁰₈₄Po

Abstract

The nucleus 21084Po has been studied in the 208Pb(α,2nγ) reaction. New levels belonging to the (h9/2, f7/2) and (h9/2, i13/2) configurations have been observed. An isomeric state at 5 057.6 keV is also proposed. The state is most likely formed by coupling the (h9/2, i13/2)11- two-proton state to the first 5- state in 208Pb.
