Abstract
Two excited superdeformed bands have been found in196Pb using the GASPγ-ray spectrometer array. They are signature-partner bands with a small signature splitting developing at higher frequencies, similar to bands 2 and 3 in the isotone194Hg. The bands are probably built on an excited neutron configuration. They show an unusual incremental alignment of 1/2ħ with respect to the194Pb core.
