Abstract：
The β⁺/EC decay of doubly odd ¹⁷⁶Ir has been investigated using ¹⁴⁶Nd(³⁵Cl, 5nγ)¹⁷⁶Ir heavy ion fusion evaporation reaction at 210MeV 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 measurements. Based on the data analysis, the previously published γ rays in ¹⁷⁶Ir decay were proved, moreover, 3 new levels and 10 new γ rays were assigned to ¹⁷⁶Ir decay. The new level scheme of ¹⁷⁶Os with low excitation energy has been established. The time spectra of typical γ rays clearly indicate a long-lived low-spin isomer in ¹⁷⁶Ir nuclide.
