Development of collective structures over noncollective excitations in Nd-139

• High-spin states in Nd-139 were investigated using the reaction Zr-96(Ca-48,5n) at a beam energy of 195 MeV and gamma-ray coincidences were acquired with the Euroball spectrometer. Apart from several dipole bands at medium excitation energy, three quadrupole bands have been observed at high spin. Linking transitions connecting two of the high-spin bands to low-energy states have been observed. Calculations based on the cranked-Nilsson-Strutinsky formalism have been used to assign configurations for the high-spin quadrupole bands.
