Abstract：
A new isotope ¹⁷⁵Er was synthesized for the first time by the ¹⁷⁶Yb(n,2p)¹⁷⁵Er reaction in irradiation of natural metal ytterbium targets with 14 MeV neutrons. The activities of ¹⁷⁵Er were observed by γ(X) ray spectroscopy. Eight new γ rays of 76.5, 120.9, 123.7, 128.5,227.3,234.0,281.4, and 1167.5 keV with half-life of 1.2±0.3 min were found and assigned to the β decay of ¹⁷⁵Er. A partial decay scheme of ¹⁷⁵Er was proposed.
