[en] The sup(144,146)Nd(α,xn) and sup(146,148)Nd(³He,xn) reactions with Esub(α) = 20 - 43 MeV and E₃sub(He) = 19 - 27 MeV are used to investigate excited states in the isotopes ¹⁴⁶Sm and ¹⁴⁷Sm. The experiments involve measurements of singles γ-ray spectra and conversion electron spectra, γ-ray angular distributions and three parameter (E sub(γ)E sub(γ) time) coincidences. From these experiments information is obtained for states with spin up to I = 13⁺ and I = 27/2^-, respectively, These states are interpeted within the framework of the cluster-vibration model (CVM) as well as the shell model.
