The neutron-rich nuclei in the lead region, beyond N=126, have been extensively studied, exploiting the fragmentation of a primary uranium beam at the FRS-RISING setup at GSI. Two isomeric states have been identified in 210Hg, the 8+ isomer expected from the seniority scheme and a second one at low spin and excitation energy. The decay strength from the 8+ isomer confirms the need of effective three-body forces in the case of neutron-rich lead isotopes. The second unexpected low-lying isomer has been tentatively assigned as a 3
