Identification of {sup 181}Hg and shape coexistence in odd-A Hg isotopes.
In-beam {gamma}-ray transitions in {sup 181}Hg, the lightest odd-A Hg isotope known thus far, have been identified from fragment mass-{gamma} and {gamma}-{gamma} coincidence measurements. Five prolate deformed rotational bands were placed in the level scheme. A decoupled band built on the strongly prolate deformed 1/2{sup -}[521] ground state was observed up to 29/2{sup -}. A 5/2{sup -}[512] configuration is suggested for a pair of strongly coupled bands displaying no signature splitting. The other two bands are also signature partner bands. They are populated with the largest intensity and exhibit splitting. They have been associated with the mixed neutron i{sub 13/2} orbitals and are proposed to decay to an i{sub 13/2} isomeric state associated with an oblate state.
