Abstract：
The γ rays following the β ⁺/EC decay of ^176,178Ir nuclei have been investigated using in-beam γ-ray experiment. In addition, with the aid of a helium-jet recoil fast tape transport system, the β ⁺/EC decay of ¹⁷⁶Ir was further studied, the new γ rays were proved and a low-spin isomer was proposed in ¹⁷⁶Ir. The isomeric state was analysized according to the systematics in neighboring nuclei.
