Abstract：
¹⁸⁹W activities were produced via the ¹⁹²Os(n, α) reaction using irradiation of isotopically enriched ¹⁹²Os metallic powder of ~100 mg/cm² with 14 MeV neutrons. The X-γ and γ-γ coincidence measurements were made so as to obtain γ rays from ¹⁸⁹W decay and its coincidence relations. A new simple decay scheme of ¹⁸⁹W including three γ rays of 210.2, 229.6 and 260.2 keV is proposed. Two new levels of ¹⁸⁹Re at 470.4 and 489.8 keV are assigned.
