Abstract
gamma-spectroscopy methods have been used to search for microsecond isomers among the fragmentation products of a 1 GeV/nucleon Pb-208 beam. In partic ular the population of the known K-pi = 35/2(-) isomer in W-179 has been in vestigated and several new isomeric decays have been found for neutron rich nuclei in the A approximate to 180-200 mass region. The ground state band of the neutron rich N = 116 system of W-190 has been identified for the fir st time and we discuss its structure in comparison to neighboring systems.
