主　　题：excitation coincidence 

摘      要：High-spin states in 178 180Ir have been studied via the 152 154Sm(31P,5nγ)reactions through excitation functions,x-γandγ-γ-t coincidence measurements.A doubly decoupled band has been identified in each of the *** level spacings for such structures in odd-odd ^(178-186)Ir have been inspected and thus a regular level staggering as a function of the neutron number is *** particular phenomenon may be associated with bandmixing at lower excitation energies.
