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.
