Title: Investigation of {sup 166}Er in the respective (n, n′γ) reaction

The spectrum, angular distribution, and linear polarization of gamma rays from the (n, n′γ) reaction on {sup 166}Er were measured in a beam of reactor fast neutrons. The known scheme of levels and gamma transitions for this nucleus was supplemented. Previously unknown gamma transitions and levels were found along with their features. The completeness of the scheme of levels whose quantum numbers J{sup π} range from 0{sup +} to 4{sup +} and whose excitation energy extends up to 1.9 MeV was established. The absence of rotational levels for the nonrotational states at 1703.11 keV (2{sup +}), 1713.42 keV (0{sup +}), and 1760.51 keV (4{sup +}) was confirmed.
