Abstract
A newly observed isomeric intruder -+ state [T-=3.5(6)ms] is identified in At203 using a gas-filled recoil separator and fusion-evaporation reactions. The isomer is depopulated through a cascade of E3 and mixed M1/E2 transitions to the 9/2- ground state, and it is suggested to originate from the π(s-)-1 configuration. In addition, the structures above the -+ state in At203 and At197 are studied using in-beam γ-ray spectroscopy, recoil-decay tagging, and recoil-isomer decay tagging methods. The -+ state is fed from 3/2+ and 5/2+ states, and the origin of these states are discussed.
