Abstract For the investigation of vibrational states in odd A nuclei we have studied the level structure of239U by the238U (n thermal,γ) reaction. Various complementary measurement techniques as curved-crystal-, anti-Compton-,γ-γ coincidence- and conversion electron spectroscopy have been applied. The resulting data have been used to establish the deexcitation scheme of239U up to ∼1.3 MeV and to make spin assignments. Most of the levels are interpreted in terms of the Nilsson model. The data also indicate the presence of the Nilsson states ¦501↺¦ and ¦750¦. Three members of theΒ-vibrational band built on the ¦631↺¦ state and one member of theΒ-vibration built on the ¦622↑¦ ground state have been identified through transitions with strongE0 admixtures. The octupole vibrational state built on the ¦631↺¦ band is proposed at 815 keV.
