Abstract

High-spin states in ²¹¹Po have been populated through the incomplete fusion reactions ²⁰⁸Pb (⁹Be,α2n) and ²⁰⁸Pb(⁷Li,p3n). The yrast sequence decaying to the τ_m = 36.4 s isomer in ²¹¹Po has been established to a spin of (43/2⁺) at an excitation energy of 4873 keV. Two other isomeric levels have been identified, with mean lives of 350(30) ns and 4(1) μs at excitation energies of 2135.7 keV and 4873.3 keV, respectively. Relationships between the structure of high-spin states in ²¹¹Po and those previously identified in ²¹⁰Po and ²¹²Po are discussed.
