Abstract
The decay of166Tm has been investigated with samples obtained by chemical extraction and mass-separation from spallation products of tantalum irradiated with 660 MeV protons. Measurements of gamma rays, γ-γ bi-dimensional coincidences, CE-γ coincidences and internal conversion electrons have been performed. About 300 γ-transitions have been observed; most of them are placed in a level scheme of166Er. The properties of some rotational and vibrational bands and of some other levels are discussed.
