Abstract
Gamma spectroscopy methods have been used to search for microsecond isomers among fragmentation products of 1 GeV/nucleon Pb-208 beam. Decays of sever al known IC-isomers in the rare earth region of A similar to 180 were obser ved, including the K = 35/2 isomer in W-179. Several new isomeric decays in the very neutron-rich systems, such as W-190, have been identified. The ob served ground state rotational band will be discussed in the framework of t he triaxial rotator model.
