Abstract：
The ¹⁷⁵Er activity was produced via the reaction ¹⁷⁶Yb(n,2p) ¹⁷⁵Er by 14MeV neutron irradiation of a natural ytterbium metal target with a thickness of～80mg/cm2.X-γ and γ-γ coincidence measurements were employed to identify ¹⁷⁵Er activity.The half-life of ¹⁷⁵Er has been determined to be (1.2±0.3)min. Eight new gamma rays were assigned to the decay of ¹⁷⁵Er. A partial decay scheme of ¹⁷⁵Er has been proposed for the first time, from which a ground rotational band has been assigned to ¹⁷⁵Tm.
