Abstract

Excited states of the neutron-deficient nucleus Hg175, populated using fusion-evaporation reactions, are reported for the first time. The spin and parity of the ground state has been determined to be Iπ=7/2− through measurements of the α decay to the daughter nucleus Pt171. A structure based on an isomeric state [T1/2=0.34(3) μs] with Iπ=13/2+ and its decay path to the ground state have been established. The observed structures are interpreted in terms of single-particle configurations, and the trends of coexisting shapes in neighboring nuclei are discussed.
