The β+/EC decay of doubly odd nucleus 176Ir has been studied via the 146Nd(35Cl, 5nγ) heavy ion fusion evaporation reaction at 210 MeV bombarding energy. With the aid of a helium-jet recoil fast tape transport system, the reaction products were transported to a low-background location for measurement. Based on the data analysis, the previously known γ rays from the decay of 176Ir are proven. Moreover, three new excited levels and ten new γ rays are assigned to 176Os. The time spectra of typical γ rays clearly indicate a long-lived low-spin isomer in 176Ir.
