Abstract：
The new neutron-rich isotope ¹⁷⁵Er activity was produced via the reaction ¹⁷⁶Yb(n,2p)by 14MeV neutron irradiation of natural ytterbium metals. When nuclide ¹⁷⁵Er decayed to its daughter nuclide ¹⁷⁵Tm, Tm characteristic X rays would be emitted with a certain ratio due to the internal conversions.So X-γ and γ-γ coincidence measurements were employed to successfully identify the neutron-rich isotope activities of rare-earth element from other rare-earth reaction products.And a partial decay scheme of ¹⁷⁵Er has been proposed for the first time.
