Beschreibungen/Notizen

• Neutron-rich nuclei in the lead region, beyond N=126N=126, have been studied at the FRS-RISING setup at GSI, exploiting the fragmentation of a primary uranium beam. Two isomeric states have been identified in super(210)Hg: the 8 super(+)8+ isomer expected from the seniority scheme in the nu g sub(9/2) nu g9/2 shell and a second one at low spin and low excitation energy. The decay strength of the 8 super(+)8+ isomer confirms the need of effective three-body forces in the case of neutron-rich lead isotopes. The other unexpected low-lying isomer has been tentatively assigned as a 3 super(-)3- state, although this is in contrast with theoretical expectations.
