The decay of the neutron-rich erbium isotope ~(175)Er is studied by using the reaction~(176)Yb(n,2p)~(175)Er.A partial decay scheme is proposed on the basis of X-γ and γ-γ coincidencemeasurements,taking into account eight observed gamma rays.A ground rotational band is as-signed to ~(175)Tm.Some systematic behaviors of 1/2+[411] ground rotational bands in odd-Athulium are described.The experimental and calculated decoupling parameters of these bandsare compared.

The decay of the neutron-rich erbium isotope ~ (175) Er is studied by using the reaction ~ (176) Yb (n, 2p) ~ (175) Er.A partial decay scheme is proposed on the basis of X-γ and gamma-gamma coincidence measurements, taking into account eight observed gamma rays. A ground rotational band is as-signed to 175 Tm. Some systematic behaviors of 1/2 + [411] ground rotational bands in odd-Athulium are described. experimental and calculated decoupling parameters of these bandsare compared.
